Delevoping cartridge B is installed on the Delevoping cartridge holding portion 130a in the rotary body C that is arranged in equipment master component A removably.This installation is performed by user.Rotary body C can be driven rotatably, and position when stopping at Delevoping cartridge B arrival precalculated position (developing location that Delevoping cartridge B is relative with photosensitive drums 107).By this operation, coupling (coupling member) 150 engages with the driving shaft 180 be arranged on equipment master component A.Further, rotary body C rotates along one direction so that Delevoping cartridge B is moved apart described precalculated position (developing location).That is, Delevoping cartridge B withdraws from precalculated position.As a result, coupling 150 moves away driving shaft 180.Coupling 150 receives the revolving force from the motor 64 (Figure 17) be arranged on equipment master component A under the state engaged with driving shaft 180.Revolving force is delivered to developer roll 110 by coupling 150.As a result, developer roll 110 rotates by the revolving force being received from equipment master component A.
As mentioned above, driving shaft 180 has pin 182 (revolving force applying portion), and is rotated by motor 64.
Material for coupling 150 is the resin material of such as polyacetal, polycarbonate or similar material.In order to strengthen the rigidity of coupling 150, also can by glass fibre or similar material being mixed in resin material to strengthen rigidity according to load torque.Further, also metal material can be adopted.Therefore, the material for coupling 150 can suitably be selected.But the coupling that resin is made can easily be processed, each Delevoping cartridge therefore in this embodiment is formed by resin material.
Coupling 150 mainly comprises three parts.
As shown in Fig. 6 (c), Part I can engage with driving shaft 180 (hereinafter will describe), and it is the secondary part 150a for receiving revolving force from the revolving force passing pin 182 (master component sideway swivel power transmitting portions) as revolving force applying portion be arranged on driving shaft 180.In addition, Part II can engage with the pin 155 be arranged on developing apparatus axle 153, and it is the drive part 150b for revolving force being delivered to developer roll 110.In addition, Part III is the center section 150c (Fig. 6 (c) and Fig. 6 (f)) for being connected to each other by secondary part 150a and drive part 150b.
As shown in Fig. 6 (f), secondary part 150a is provided with the driving shaft insertion opening part 150m expanded towards rotation L2.Drive part 150b has developing apparatus axle insertion opening part 150l.
Open 150m to be limited by the taper driving shaft receiving surface 150f expanded towards driving shaft 180 (Fig. 9 to 13) side.Receiving surface 150f forms recess 150z, as shown in Fig. 6 (f).Recess 150z comprises and is positioned at the opening 150m with developer roll 110 opposite location relative to axis L2 direction.
Like this, no matter which kind of rotatable phase developer roll 110 is in Delevoping cartridge B, and coupling 150 can not transmit Angle Position (Figure 22 (d)) and depart between Angle Position (Figure 25 (a) (d)) move (pivotable) at the pre-joint Angle Position (Figure 22 (a)) of the axis L3 relative to driving shaft 180, revolving force interferingly by driving shaft 180 free end 182a.Hereinafter its details will be described.
On the end face of recess 150z, multiple projection (bonding part) 150d (150d1-150d4) equally spaced arranges one circumferentially around axis L2.Intake section 150k (150k1,150k2,150k3,150k4) is provided with between adjacent protrusions 150d.Interval between adjacent protrusions 150d1-150d4 is larger than the external diameter of pin 182, thus receives the revolving force passing pin 182 (revolving force applying portion) be arranged on driving shaft 180.Pin is revolving force applying portion.Recess between adjacent protrusions is described intake section 150k1-150k4.When revolving force is delivered to coupling 150 from driving shaft 180, pin 182 is by the arbitrary receiving in intake section 150k1-150k4.In addition, in Fig. 6 (d), revolving force receiving surface (revolving force receiving unit) 150e (150e1-150e4) is arranged on the upstream end relative to clockwise direction (X1) of each projection 150d.Revolving force receiving surface 150e1-150e4 is along extending with the direction of coupling 150 sense of rotation traversed by.More specifically, projection 150d1 has receiving surface 150e1, and projection 150d2 has receiving surface 150e2, and projection 150d3 has receiving surface 150e3, and projection 150d4 has receiving surface 150e4.Under the state that driving shaft 180 rotates, pin 182a1,182a2 contact the arbitrary surface in receiving surface 150e.By doing like this, the receiving surface 150e contacted by pin 182a1,182a2 is pushed by pin 182.Like this, coupling 150 rotates around axis L2.
In order to as far as possible stably transmitting torque is delivered to coupling 150, it is desirable to revolving force receiving surface 150e to be arranged on a center of circle O and being positioned at imaginary circle (same circumference) upper (Fig. 6 (d)) on axis L2.Like this, revolving force transmits constant-radius, and the torque being delivered to coupling 150 is stablized.In addition, for projection 150d, come the position of stable coupling 150 preferably by the dynamic balance making coupling 150 receive.Therefore, in this embodiment, receiving surface 150e is all arranged on position (180 degree) diametrically.More specifically, in this embodiment, relative to each other diametrically, receiving surface 150e2 and receiving surface 150e4 relative to each other diametrically for receiving surface 150e1 and receiving surface 150e3.By this configuration, the power that coupling 150 receives forms couple.Therefore, coupling 150 can by means of only reception couple with regard to continuous rotating motion.Therefore, without the need to specifying the position of coupling 150 on its rotation L2, coupling 150 just can rotate.In addition, as the quantity of receiving surface, as long as the pin of driving shaft 180 182 (revolving force applying portion) can enter intake section 150k (150k1-150k2), just can suitably select.In this embodiment, as shown in Figure 6, four receiving surfaces are provided with.This embodiment is not limited to this example.Such as, receiving surface 150e (projection 150d1-150d4) need not be arranged on same circumferentially (on the imaginary circle C1 of Fig. 6 (d)).Or, position diametrically need not be arranged on.But, receiving surface 150e is set as described above, above-mentioned effect can be provided.
At this, in this embodiment, the diameter of pin is about 2mm, and the circumferential length of intake section 150k is about 8mm.The circumferential length of intake section 150k is the interval of (in imaginary circle) between adjacent protrusions 150d.These sizes are not used for limiting the present invention.
Similar to opening 150m, developing apparatus axle insertion opening part 150l has taper revolving force receiving surface 150i, and it is expanded towards developing apparatus axle 153 as an expansion.Receiving surface 150i forms recess 150q, as shown in Fig. 6 (f).
Like this, no matter which kind of rotatable phase developer roll 110 is in Delevoping cartridge B, and coupling 150 can not transmit Angle Position relative to axis L1 at revolving force, engage between Angle Position and disengaging Angle Position and move (pivotable, swing) in advance interferingly by the free end of developing apparatus axle 153.In the example shown in the series of figures, recess 150q is made up of the tapered receiver surface 150i be centrally located on axis L2.Stand-by opening 150g1 or 150g2 (" opening ") (Fig. 6 (b)) is provided with in receiving surface 150i.For coupling 150, pin 155 can insert the inner side of this opening 150g1 or 150g2, makes it can be installed in developing apparatus axle 153.Further, the size of opening 150g1 or 150g2 is larger than the external diameter of pin 155.By doing like this, no matter which kind of rotatable phase developer roll 110 is in Delevoping cartridge B, and coupling 150 can transmit Angle Position when the interference not by pin 155 at revolving force and engage in advance between Angle Position (or departing from Angle Position) as described later and move (pivotable, swing).
More specifically, the free end of projection 150d and recess 150z is adjacent to arrange.Further, the crisscross of the sense of rotation traversed by that projection (outshot) 150d edge rotates with coupling 150 is given prominence to, and arranges at certain intervals along described sense of rotation.Further, under the state that Delevoping cartridge B is installed on rotary body C, receiving surface 150e joins or abuts to pin 182 to, and is pushed by the pin 182 from rotating driveshaft reception.
Like this, receiving surface 150e receives revolving force from driving shaft 180.In addition, receiving surface 150e is all equidistantly arranged with axis L2, and arranges in couples about axis L2.Described receiving surface 150e forming along described crisscross surface by projection 150d.In addition, intake section (recess) 150k is arranged along sense of rotation, and they are recessed in the direction of axis L2.
Intake section 150k is formed as the interval between adjacent protrusions 150d.Under driving shaft stops the state that it rotates, Delevoping cartridge B is installed on rotary body C, when coupling engages with driving shaft 180, pin 182 enters intake section 150k.Further, the pin 182 of the driving shaft 180 of rotation pushes receiving surface 150e.Or when coupling engages with driving shaft 180 and driving shaft 180 rotates, pin 182 enters intake section 150k and pushes receiving surface 150e.
Like this, coupling 150 rotates.
Revolving force receiving surface (revolving force receiving member (part)) 150e can be arranged on the inside of driving shaft receiving surface 150f.Or receiving surface 150 can be arranged at relative to axis L2 direction in receiving surface 150f part outwardly.When receiving surface 150e is arranged at inside receiving surface 150f, intake section 150k is arranged at inside receiving surface 150f.
More specifically, intake section 150k is the recess between the inner side of the arch section being arranged at receiving surface 150f, projection 150d.In addition, when receiving surface 150e is arranged on position outwardly, intake section 150k is the recess between projection 150d.At this, recess can be the through hole extended along axis L2 direction, or it can be closed at its one end place.More specifically, recess is provided by the area of space be arranged between projection 150d.Necessary just can make pin 182 enter in this region under the state that Delevoping cartridge B is installed on rotary body C.
These structures of wait part can be applied to the embodiment hereinafter will described equally.
In Fig. 6 (e), revolving force transmits the upstream relative to counter clockwise direction (X2) that surface (revolving force transmitting portions) 150h (150h1 or 150h2) is arranged at opening 150g1 or 150g2.Further, revolving force is delivered to developer roll 110 by the transmitting portions 150h1 contacted with pin 155a1,155a2 or 150h2 from coupling 150.More specifically, the side surface of surperficial 150h1 or 150h2 pushing pin 155 is transmitted.Like this, the mode that coupling 150 is just aimed at axis L2 with its center rotates.Transmit surperficial 150h1 or 150h2 along extending with the direction of the sense of rotation traversed by of coupling 150.
Similar to projection 150d, it is desirable to surperficial for transmission 150h1 or 150h2 to be relative to each other arranged on circumferentially same diametrically.
When with injection moulding manufacture drum coupling member 150, center section 150c can be thinner.Driving force receiving unit 150a, drive part 150b and center section 150c is made to have roughly uniform thickness this is because coupling will manufacture.Therefore, when the insufficient rigidity of center section 150c, center section 150c can be made thicker, thus make secondary part 150a, drive part 150b and center section 150c have roughly equal thickness.
(6) shape of supporting member
See Fig. 7, supporting member (installation component) 157 will be described below.Fig. 7 (a) is the stereographic map observed from drive shaft side, and Fig. 7 (b) is the stereographic map observed from developer roll side.
Supporting member 157 has maintenance coupling 150 and Delevoping cartridge B is positioned the function in rotary body C.Further, it have support coupling 150 make revolving force can be delivered to the function of developer roll 110.
More specifically, coupling 150 is installed on Delevoping cartridge B by supporting member 157.
As shown in Figure 7, supporting member comprises and in the process at installation and removal Delevoping cartridge B, carries out the guidance part 140L2 that guides relative to the holding portion 130a be arranged on rotary body C and for Delevoping cartridge B being positioned the trunk portion 140L1 in holding portion 130a.Further, above-mentioned coupling 150 is arranged in the inner space 157b of the cylindrical portion 157c coaxially arranged with developer roll (not shown).At the inner peripheral surface 157i place of Special composition 157b, be provided with rib 157e1 and 157e2 for being held in by coupling 150 in Delevoping cartridge B.Rib 157e1 and 157e2 is arranged relative to one another relative to the moving direction X4 (sense of rotation of rotary body C) of Delevoping cartridge B.Supporting member 157 is provided with localization part 157d1 and 157d2 for himself being fixed to developing device frame 113, and is provided with hole 157g1 and 157g2 that fixed screw is passed.
(6) coupling is relative to the supporting construction of Delevoping cartridge framework
See Fig. 8 to Figure 13, developer roll 110 and coupling 150 supporting construction (mounting structure) relative to developing device frame (Delevoping cartridge framework) 113 will be described.Fig. 8 is from the enlarged drawing of the critical piece near the developer roll of driving side observation, Delevoping cartridge.Fig. 9 be along Fig. 8 S4-S4 crossed by cut-open view.Figure 10 is along the cut-open view crossed by development axis L1, it illustrates the state before coupling and supporting member installation.Figure 11 be installation is shown after the cut-open view of state.Figure 12 be the axis L2 of coupling and developer roll axis L1 roughly coaxial alignment time cut-open view.Figure 13 illustrates cut-open view coupling being rotated through the state after 90 degree from the state of Figure 12.Figure 14 is the stereographic map of the assembled state that development roll shaft and coupling are shown.Figure 14 (b1) is stereographic map to (b5), and Figure 14 (a1) to (a5) is the view observed from axis L1 direction.
As shown in figure 14, coupling 150 is mounted to its axis L2 can be tilted along any direction relative to the axis L1 of development roll shaft 153 (developer roll).
In Figure 14 (a1) and Figure 14 (b1), the axis L2 of coupling 150 is coaxial with the axis L1 of development axle 153.Coupling 150 from the acclivitous state of this state shown in Figure 14 (a2) and Figure 14 (b2).As shown in these figures, when axis L2 rolls oblique towards opening 150g, when relatively observing these components based on coupling, sell mobile in opening 150g inside.As a result, coupling 150 tilts around the axis AX (Figure 14 (a2)) perpendicular to opening 150g.
In Figure 14 (b3), the state that coupling 150 is tilted to the left is shown.As shown in the drawing, when axis L2 along opening 150g orthogonal directions tilt time, when relatively observing these components based on coupling, sell at opening 150g internal rotating.Rotation is the axis AY (Figure 14 (a3)) of passing pin 155.
Illustrate respectively in Figure 14 (a4) and (b4) with Figure 14 (a5) and (b5) coupling 150 downwards with the state be tilted to the right.Coupling 150 tilts around each axis AX and AY.
On the direction different from described vergence direction above, such as, centre position in the centre position of the vergence direction of Figure 14 (a2) and 14 (a3), in the centre position of the vergence direction of Figure 14 (a3) and 14 (a4), at the vergence direction of Figure 14 (a5) and 14 (a2), by realizing above-mentioned inclination by the rotation combination along rotation AX and AY direction.Therefore, axis L2 can relative to axis L1 along any direction pivotable.Now, pin 155 is arranged on development roll shaft 153.More specifically, pin 155 is from the outer surface projection of development roll shaft 153.The coupling 150 be oppositely arranged with pin 155 is provided with opening 150g.When the size of opening 150g is configured such that proper axis L2 tilts relative to axis L1 opening and pin non-interference.
More specifically, transmit surface (revolving force transmitting portions) 150h can move (Figure 14) relative to pin (revolving force receiving unit) 155.Pin 155 has transmission surface 150 under situation of movement.Further, transmit surperficial 150h and pin 155 to be engaged with each other along the sense of rotation of coupling 150.Further, between the surperficial 150h of transmission and pin 155, gap is provided with.Like this, coupling 150 all can move (can pivotable, can swing) along the substantially all directions relative to axis L1.
Being referred to axis L2 can the crooked or inclination along any direction relative to axis L1.But axis L2 not necessarily will tilt to predetermined angular in the scope internal linear in 360 degree of whole directions of coupling 150.Such as, opening 150g can be selected, make it circumferentially slightly wide.Like this, during relative to axis L1 tilt axis L2, even if when axis L2 can not tilt to predetermined angular linearly, coupling 150 also can rotate the small number of degrees around axis L2.Therefore, it can tilt to predetermined angular.In other words, if needed, the play amount along sense of rotation of opening 150g can suitably be selected.
In this way, coupling 150 maybe can swing whole circumferentially can the rotation of cardinal principle relative to the axis L1 of developer roll 110.More specifically, coupling 150 all circumferentially can pivotable in the cardinal principle of coupling 150 relative to drum axle 153.
And then can understand from foregoing explanation, coupling 150 also can circle round roughly throughout the circumferential along the circumference of drum axle 153.At this, " convolution " is mobile does not refer to the movement that coupling itself rotates around axis L2, and refer to the movement that tilt axis L2 rotates around the axis L1 of developer roll, but " convolution " herein does not get rid of the rotation of coupling around the axis L2 of coupling 150 itself.
Mention, axis L2 can the crooked or inclination along any direction relative to axis L1.But axis L2 not necessarily wants can in scope internal linear ground, the whole 360 degree of directions predetermined oblique angle of coupling 150.Such as, opening 150g can be selected, make it circumferentially slightly wide.Like this, when axis L2 tilts relative to axis L1, even if when it can not tilt to predetermined angular linearly, coupling 150 also can rotate the small number of degrees around axis L2.Therefore, it can tilt to predetermined angular.In other words, if needed, can suitably select opening 150g along the play amount of sense of rotation, in this way, coupling 150 can substantially all circumferentially rotate relative to drum axle (revolving force receiving member) 153 or swing.More specifically, coupling 150 can in the whole circumferentially pivotable of the cardinal principle of coupling 150 relative to drum axle 153, and then as can be understood from foregoing explanation, coupling 150 also roughly circumferentially can circle round in drum all of axle 153 along the circumference of drum axle 153.At this, " convolution " is mobile does not refer to the movement that coupling itself rotates around axis L2, and refer to the movement that tilt axis L2 rotates around the axis L1 of photosensitive drums, but " convolution " herein does not get rid of the rotation of coupling around the axis L2 of coupling 150 itself.
In addition, the scope of " can along substantially all directions move " refers to following scope: within the scope of this, when Delevoping cartridge B is installed on equipment master component A by user, which kind of phase place the driving shaft no matter with revolving force applying portion is in, and coupling all can move to revolving force and transmit Angle Position.In addition, the scope of " can along substantially all directions move " also refers to following scope simultaneously: within the scope of this, when coupling and driving shaft depart from, and whether be in angular stop phase place regardless of driving shaft, coupling all can move to disengaging Angle Position.
In addition, coupling is provided with gap between revolving force receiving unit (such as pin 155) in other words in revolving force transmitting portions (such as revolving force transmits surperficial 150h) and revolving force transmitting portions to be joined, makes it can along all directions pivotable substantially relative to axis L1.In this way, coupling is installed on the end of Delevoping cartridge B.Therefore, coupling can move along all directions substantially relative to axis L1.
This structure to hereinafter by similar for the structure in the embodiment of coupling that describes.
Assemble method will be described below.
After developer roll 110 is rotatably installed on developing device frame 113, pin 155 is installed on development axle 153.Thereafter, developing gear 145 is assembled on development axle 153.
Thereafter, as shown in Figure 10, coupling 150 and supporting member 157 insert along direction X3.First, while keeping axis L2 and the X3 of coupling 150 parallel, the downstream of coupling 150 towards direction X3 is inserted.Now, the phase place of pin 155 of axle 153 of developing and the phase place of the opening 150g of coupling 150 match each other, in pin 155 insertion opening 150g1 or 150g2.Further, the free end 153b of axle 153 is developed against the receiving surface 150i of coupling 150.The free end 153b of development axle 153 is spherical surfaces, and the receiving surface 150i of coupling 150 is trochoidal surfaces.Therefore, the drive part 150b side of coupling 150 navigates to the center (center of spherical surface) of the free end 153b of development axle 153.As described later, when coupling 150 rotates because of the transmission of the driving force (revolving force) from equipment master component A, contact revolving force is transmitted surperficial 150h1 or 150h2 (Fig. 6 (b)) by the pin 155 be positioned in opening 150g.Like this, just revolving force can be transmitted.Thereafter, an end face 157w of supporting member 157 inserts towards the downstream of direction X3.Like this, a part for coupling 150 is contained in the space segment 157b of supporting member 157.Further, supporting member 157 is fixed in developing device frame 113, because which form overall Delevoping cartridge B.
Be described to the size of coupling 150 each several part.As shown in Figure 10, the maximum outside diameter of the secondary part 150a of coupling 150 is Φ D2, and the maximum outside diameter of drive part 150b is Φ D1, and the minor diameter of opening 150g is Φ D3.In addition, the maximum outside diameter of pin 155 is pin Φ D5, and the internal diameter of the holding rib 157e of supporting member 157 is Φ D4.At this, " maximum outside diameter " is the external diameter of the maximum rotational trajectory of rotation L1 around developer roll 110.The maximum outside diameter Φ D1 relevant to coupling 150 and Φ D3 is the external diameter of the maximum rotational trajectory around axis L2.Now, because meet Φ D5 < Φ D3, therefore coupling 150 is assembled into precalculated position by straight installation operation along direction X3, and therefore assembling property is high.The inner surface diameter Φ D4 of the holding rib 157e of supporting member 157 is larger than the Φ D2 of coupling 150, less than Φ D1 (Φ D2 < Φ D4 < Φ D1).Like this, only supporting member 157 just need be enough to be assembled into precalculated position along the step of the straight assembling of direction X3.Therefore, assembling property (state after assembling shown in Figure 11) can be improved.
As shown in figure 11, the holding rib 157e of supporting member 157 is arranged along the flange portion 150j of the adjacent coupling 150 in axis L1 direction.More specifically, on the direction of axis L1, the distance from the end face 150j 1 of flange portion 150j to the axis of pin 155 is n1.In addition, the distance of the other end 157j2 from the end face 157e1 of holding rib 157e to flange portion 150j is n2.Meet following relation: distance n2 < distance n1.
In addition, for the vertical direction of axis L1, flange portion 150j and rib 157e1,157e2 are arranged so that they are overlapping toward each other.More specifically, the distance n4 (lap) of the outside surface 150j3 from the inside surface 157e3 of rib 157e to flange portion 150j is the lap n4 of the orthogonal directions relative to axis L1.
By setting like this, pin 155 is prevented to depart from from opening 150g.That is, the movement of coupling 150 is limited by supporting member 157.Therefore, coupling 150 can not depart from Delevoping cartridge.This prevents disengaging method from just can realize without the need to optional feature.Above-mentioned size is wished from reduction manufacture and assembly cost angle.But the present invention is not limited to these sizes.
As above with reference to as described in Fig. 9,11 and 12, the recess 150q of coupling 150 and receiving surface 150i contacts free end surface 153b and the projection of development axle 153.Therefore, coupling 150 swings along free end (spherical surface) 153b around the center P2 of free end (spherical surface) 153b, and in other words, no matter which kind of phase place drum axle 153 is in, and axis L2 can both move along all directions substantially.The axis L2 of coupling 150 can move (pivotable, rotation, movement) along all directions substantially.As hereinafter described, in order to make coupling 150 can engage with driving shaft 180, before will engaging, axis L2 will tilt relative to the downstream of rotary body C sense of rotation relative to axis L1 court.In other words, as shown in figure 17, axis L2 is inclined to the downstream place making the secondary part 150a of coupling 150 be positioned at the sense of rotation X4 relative to rotary body.
To be further described in more detail below.
As shown in figure 12, select the distance n3 between the maximum outside diameter part of the drive part 150b of coupling 150 and supporting member 157, make to be provided with minim gap between maximum outside diameter part and supporting member 157.Like this, coupling 150 can pivotable.
As shown in Figure 7, rib 157e1 and 157e2 be parallel to the axis L1 extend semicircle rib.Rib 157e1 and 157e2 is perpendicular to sense of rotation X4.
In addition, shorter to the distance n1 of drive part 150b lateral edges than the center of pin 155 to the distance n2 (Figure 11) of flange portion 150j along axis L1 direction from rib 157e.Like this, pin 155 would not depart from opening 150g1 and 150g2.Therefore, as shown in Figure 9, secondary part 150a can along direction X4 pivotable significantly relative to the axis L2 of coupling 150.In other words, drive part 150b can towards side (perpendicular to the accompanying drawing page) pivotable not significantly being provided with rib 157e.Fig. 9 illustrates the state after axis L2 inclination.In addition, the state that coupling 150 also can tilt from axis L2 as shown in Figure 9 moves to the state almost parallel with axis L1 as shown in figure 12.Rib 157e1 and 157e2 is set in this way.By doing like this, make the axis L2 of coupling 150 relative to axis L1 pivotable, in addition, can prevent developing device frame 113 and coupling 150 from departing from.Two kinds of effects can provide.
Coupling 150 has play (distance n2) relative to development axle 153 along axis L1 direction.Therefore, receiving surface 150i (conical surface) can not be contact drum axle free end 153b (spherical surface) closely always.In other words, pivoting centre can depart from the center of curvature P2 of spherical surface.But even if under these circumstances, axis L2 still can rotate or pivotable relative to axis L1.Therefore, the object of this embodiment can be realized.
In addition, the maximum possible inclined angle alpha (Fig. 9) between axis L1 and axis L2 is constrained to 1/2nd of the bevel angle (α 1, Fig. 6 (f)) between axis L2 and receiving surface 150i.The drift angle of the cone shape of the receiving surface 150i of coupling 150 can suitably be selected.By doing like this, the inclined angle alpha of coupling 150 can be set as optimal value.The shape of the cylindrical section 153a of development axle 153 may simply be cylindrical.Like this, manufacturing cost can be saved.
Select the width being in the opening 150g of dormant state, the pin 155 when axis L2 tilts can not be interfered, as mentioned before.
The track of flange portion 150j when tilting along direction X5 in secondary part 150a side is illustrated by the region T1 in Figure 13.As shown in the figure, even if coupling 150 tilts, the interference with pin 155 also can not occur, therefore, flange portion 150j can be arranged at coupling 150 whole circumferentially (Fig. 6 (b)).In other words, axle receiving surface 150i has coniform shape, and therefore, when coupling 150 tilts, pin 155 does not enter in the T1 of region.Therefore, the excision extension of coupling 150 minimizes.Therefore, the rigidity of coupling 150 can be guaranteed.
(7) description of the structure of the rotary body (mobile member, rotation selection mechanism) of equipment master component
Next with reference to Figure 15 to 21, the structure as the rotary body C of mobile member is described.Figure 15 and 16 is the stereographic maps of the rotary body C under the state of not installing Delevoping cartridge B.Figure 17 A illustrates that single Delevoping cartridge B is installed on the stereographic map of the state of rotary body C.Figure 18 to 21 is side views that rotary body C, photosensitive drums 107, drivetrain and Delevoping cartridge B are shown.
Along axis L1 direction, rotary body flange 50L and 50R is arranged on two ends.Rotary body side plate 54L and 54R is respectively arranged with in the outside along axis L1 direction of rotary body flange 50L and 50R.Rotary body flange 50L and 50R and central shaft 51 thereof rotatably support along outermost side plate 54L and 54R in axis L1 direction by being positioned at.
At relative surperficial 50Lb and the 50Rb place of paired flange 50L with 50R, be provided with for mounting and dismounting channel form master component guide member 130L1,130L2,130L3,130L4,130R1,130R2,130R3 and 130R4 of using in the process of Delevoping cartridge B relative to rotary body C (holding portion 130A).The master component guide member that box side guide member 140R1,140R2,140L1 and 140L2 (Fig. 2 and 3) of box B are arranged on equipment master component A along these inserts.That is, Delevoping cartridge B can be installed on rotary body C and also can dismantle from rotary body C.Delevoping cartridge B is installed on rotary body C with removable under type by user.
More specifically, in an end relative to Delevoping cartridge B (B1) longitudinal direction of Delevoping cartridge B (B1), guide member 140R1 and 140R2 is provided with.Further, at another longitudinal end place of Delevoping cartridge B (B1), guide member 140L1 and 140L2 is provided with.User holds Delevoping cartridge B, and guide member 140R1 and 140R2 is inserted the guide member 130R1 be arranged on rotary body C.Similarly, guide member 140L1 and 140L2 is inserted the guide member 130L1 be arranged on rotary body C by user.In this way, Delevoping cartridge B is removably installed on the holding portion 130A be arranged on rotary body C by user.That is, Delevoping cartridge B is guided by above-mentioned guide member, and along being installed on holding portion 130A with the direction of the longitudinal direction traversed by of Delevoping cartridge B (developer roll 110) and dismantling from holding portion 130A.Delevoping cartridge B installs along following direction: wherein, and longitudinal direction intersects with the sense of rotation X4 of rotary body C.Therefore, the Delevoping cartridge B (coupling) being arranged on a longitudinal end place of Delevoping cartridge B is moved along the direction being approximately perpendicular to driving shaft 180 by the rotation of rotary body C.When revolving force is delivered to Delevoping cartridge B from equipment master component A, the Delevoping cartridge B be installed on rotary body C tends to rotate around arc guide member 140R1 and 140L1.But elongate guide 140R2 contacts the inside surface of the groove of guide member 130R1 and 130L1 with 140L2, Delevoping cartridge B can be located relative to rotary body C.That is, Delevoping cartridge B is removably contained in holding portion 130A.
Similarly, Delevoping cartridge B (B2) is guided by guide member 130R2 and 130L2 be arranged on rotary body C, and is removably installed on holding portion 130A.Delevoping cartridge B (B3) is guided by guide member 130R3 and 130L3 be arranged on rotary body C, and is removably installed on holding portion 130A.Delevoping cartridge B (B4) is guided by guide member 130R4 and 130L4 be arranged on rotary body C, and is removably installed on holding portion 130A.
That is, Delevoping cartridge B is removably installed on by user in the holding portion 130A that is arranged on rotary body C.
Figure 17 illustrates that Delevoping cartridge B is installed on the state in equipment master component A (rotary body C).
Each Delevoping cartridge B locates relative to rotary body C, and is rotated by the rotation of rotary body C.Now, Delevoping cartridge B is fixed to rotary body C by loading spring, locking device or similar device (not shown), and the position of Delevoping cartridge B is not departed from because of the rotation of rotary body C.
Another rotary body side plate 54L is provided with the driving mechanism for rotating developer roll (not shown).That is, developing apparatus driven wheel 181 engages the pinion wheel 65 be fixed on the motor drive shaft of motor 64.When motor starts to rotate, revolving force is delivered to gear 181.Start to rotate with the coaxial driving shaft 180 arranged of gear 181.As a result, the revolving force of driving shaft 180 is delivered to parts such as developer roll 110 grade by coupling 150.Say one along band, in this embodiment, driving shaft 180 had started to rotate before coupling 150 engages.But the rotation start time of driving shaft 180 can suitably be selected.
Delevoping cartridge B rotates together with paired rotary body flange 50L with 50R.That is, when rotary body C rotates predetermined angular, rotary body C just stops it rotating.As a result, Delevoping cartridge B is just positioned at position (developing location) place relative with the photosensitive drums 107 be arranged on equipment master component A.With the location of Delevoping cartridge B with stop substantially side by side, coupling 150 engages drive shaft 180.That is, recess 1502 covers the end of the end 180b of driving shaft 180.
Driving shaft 180 has the structure roughly the same with above-mentioned development axle.That is, driving shaft 180 pin 182 that comprises ball-shaped end 180b and pass at the general center place of the major part 180a of cylinder form.By means of this pin 182, revolving force (driving force) is delivered to Delevoping cartridge B by coupling 150.
Rotary body C installs the Delevoping cartridge B of four kinds of colors.At this, Delevoping cartridge B performs in the following manner to exerting pressure of photosensitive drums 107.
As mentioned above, flange 50L and 50R is rotatably supported by rotary body side plate 54L and 54R.Rotary body side plate 54L and 54R being positioned at two ends is located by the swingable axle 60 be rotatably arranged on above rotary body side plate 54L and 54R and is fixed to the side plate (not shown) of equipment master component A.In other words, Delevoping cartridge B, rotary body flange 50 and rotary body side plate 54 swing integratedly around swingable axle 60.That is, Delevoping cartridge B and rotary body C swings integratedly.As a result, Delevoping cartridge B is pressed against in photosensitive drums 107 or with photosensitive drums 107 and is separated.
Thisly to be pressed against and lock out operation extrudes by the rotation of cam (not shown) the rotator support 66 that is arranged between rotary body side plate 54L and 54R and carries out.
Further, as described in Figure 15, driving shaft 180 is roughly relative to radial and axial location and the precalculated position being arranged on equipment master component A.Further, Delevoping cartridge B is also stopped by the rotation of rotary body C and is positioned at the precalculated position of equipment master component A.These oriented driving shafts 180 are connected by coupling 150 with Delevoping cartridge B.Coupling 150 can swing (can pivotable, can move) relative to Delevoping cartridge B (framework).Therefore, even if be positioned between the driving shaft 180 in precalculated position and the Delevoping cartridge B being positioned at precalculated position, coupling 150 also can transmit revolving force reposefully.That is, even if when there is some axles (axis) skew between driving shaft 180 and Delevoping cartridge 150, coupling 150 also can transmit revolving force reposefully.
This is one of remarkable result of the embodiment applying coupling of the present invention.
(8) switching construction of Delevoping cartridge (developing apparatus)
At the respective outer surface place of flange 50L and 50R, be provided integrally with gear 50a, as shown in Figure 15 to 17.A pair idle pulley 59L and 59R engaged with these gears 50a is arranged on two longitudinal end places.These idle pulleys 59L with 59R is connected by swingable axle 60.When the flange 50L being arranged on a longitudinal end place rotates, another flange 50R is in phase rotated by gear 59L and 59R.By adopting this drives structure, in the rotation of rotary body C or the rotary course of developer roll 110, prevent the arbitrary distortion in flange 50L and 50R.
Rotary body driven wheel 65 engages with gear 59L and 59R in the oscillation centre (getting final product axis of swing 60) being connected to rotary body side plate 54L and 54R.This gear 65 is connected to motor 61.Scrambler 62 is installed on the turning axle of motor 61.Scrambler 62 detects the rotation amount of motor 61, and controls revolution.Further, at the outer surface place of a flange 50L, be provided with the dimmer 57 (Figure 16) radially given prominence to from flange 50L.Flange 50L and dimmer 57 rotate with the light isolating switch 58 through being fixed on side plate 58.Be blocked device 57 and block by detecting light isolating switch and control to make it rotate predetermined angular to rotary body C at every turn.That is, after rotary body C rotates predetermined angular from the time of dimmer 57 shading light isolating switch, the first Delevoping cartridge stops at the position relative with photosensitive drums 107.Rotary body C rotates predetermined angular along one direction further, and the second Delevoping cartridge stops at the position relative with photosensitive drums 107 thereafter.By altogether repeating four this operations (repeating the stopping of the Delevoping cartridge of four kinds of colors), just define coloured image.
That is, under the state that Delevoping cartridge B is installed on rotary body C, by rotary body C along unidirectional rotation, Delevoping cartridge B moves along the direction vertical with the axis L3 of driving shaft 180.
At the upper surface place of equipment master component A, be provided with the opening for being mounted and dismounted Delevoping cartridge B by user and the lid 40 (Fig. 4) can opened/can close for covering this opening.Further, the door switch (not shown) of the opening/closing for detecting lid 40 is provided with.During being energized and when lid 40 closes (at this moment door switch operation), start the rotation process of rotary body C.
(9) location structure during blocked operation of Delevoping cartridge (developing apparatus)
The operation of rotary body C and Delevoping cartridge B is described step by step below with reference to Figure 18 to 21.For ease of describing, a Delevoping cartridge of a rotating body is only shown.
First, under the state shown in Figure 18, Delevoping cartridge B does not arrive precalculated position (coupling member 150 is positioned at pre-rotation Angle Position).When rotary body C rotates along the direction of X4, the dimmer 57 given prominence to the above-mentioned outer peripheral surface portion from rotary body flange 50 arrives light isolating switch 58, makes rotary body C stop at precalculated position (state as shown in Figure 19).Now, the coupling 150 of driving shaft 180 and Delevoping cartridge B is connected to each other (coupling member 150 is positioned at revolving force and transmits Angle Position).Under developer roll 110 is placed in revolvable state.In this embodiment, when coupling 150 starts the state with the joint of driving shaft 180, driving shaft 180 rotates.Therefore, developer roll 110 rotates.But engage with driving shaft 180 at coupling 150, driving shaft 180 is when stopping, coupling 150 can waited under rotation status.Hereinafter the joint (be connected) of coupling 150 with driving shaft 180 will be described in detail in detail.
Then, as mentioned above, actuating cam (not shown), to contact rotator support 66, makes rotary body C move widdershins around swingable axle 60.That is, developer roll 110 contacts photosensitive drums 107 (state of Figure 20) by moving along X1 direction.Then, predetermined imaging operation is performed.
After completing imaging operation, rotary body C is rotated in a clockwise direction around swingable axle 60 by the power of spring (not shown).Therefore, rotary body C returns to the state shown in Figure 19.That is, developer roll 110 moves apart photosensitive drums 107 (coupling 150 is positioned at and departs from Angle Position).
Then, rotary body C rotates along X4 direction around central shaft 51, makes Delevoping cartridge B subsequently can arrive developing location (state of Figure 21).Now, the connection between driving shaft 180 and coupling 150 is released.That is, coupling 150 is separated with driving shaft 180.Operation now will specifically describe below.
To the aforesaid operations with reference to the operation described in Figure 21, four times are repeated altogether for four kinds of colors from reference to the operation described in Figure 18, thus realize colour imaging.
(10) bonding operation/revolving force transmission/disengaging operation of coupling
As mentioned before, just stop at the precalculated position of equipment master component A at Delevoping cartridge B before or with this stopping substantially side by side, coupling 150 engages (from Figure 18 to Figure 19) with driving shaft 180.Further, when after the rotation of predetermined amount of time, Delevoping cartridge B moves apart the precalculated position of equipment master component A, coupling 150 and driving shaft 180 depart from (from Figure 20 to Figure 21).
See Figure 22 to Figure 25, will bonding operation, the revolving force transmission operation of coupling be described and depart from operation.Figure 22 is the longitudinal sectional view that driving shaft, coupling and development axle are shown.Figure 23 is the longitudinal sectional view that phase differential between driving shaft, coupling and development axle is shown.Figure 25 is the longitudinal sectional view that driving shaft, coupling and development axle are shown.
Move on in the process of developing location at Delevoping cartridge B by the rotation of rotary body C, coupling 150 is positioned at and engages Angle Position in advance.More specifically, the axis L2 of coupling tilts relative to the axis L1 of development axle 153 in advance, makes secondary part 150a be positioned at the downstream of rotary body sense of rotation X4.By this inclination of coupling 150, relative to the direction of axis L1, the position of free end position, the downstream 150A1 for the sense of rotation X4 of rotary body C of coupling 150 than free end 180b3 closer to development axle 153 side place.In addition, on the direction of axis L1, the position of free end position, the upstream 150A2 for the X4 of direction than driving shaft free end 180b3 closer to pin 182 side place (Figure 22 (a), (b)).At this, free end position refers to the position closest to driving shaft for the axis L2 direction of the secondary part 150a of the coupling 150 shown in Fig. 6 (a) and 6 (c), and it is distance axis L2 position farthest.In other words, according to the rotatable phase of coupling (Fig. 6 (a) and the 150A in (c)), free end position is the edge line of the secondary part 150a of coupling 150, or the edge line of driven protuberance 150d.
First, pass through from axle free end 180b3 side relative to free end position, the downstream 150A1 of rotary body sense of rotation (X4).Further, at coupling 150 from driving shaft 180 side through afterwards, the receiving surface 150f of the cone shape of coupling 150 or projection 150d contact free end 180b or the pin 182 of driving shaft 180.Further, it tilts in response to the rotation of rotary body C, and axis L2 is become parallel with axis L1 (Figure 22 (c)).Further, finally, being determined relative to the position of equipment master component A of Delevoping cartridge B.More specifically, rotary body C stops.In this case, driving shaft 180 is coaxial roughly each other with development axle 153.More specifically, coupling 150 moves on to revolving force transmission Angle Position from the pre-Angle Position that engages, and walks around (pivotable and swing) from driving shaft 180 side to allow its free end position 150A1.Further, coupling 150 transmits Angle Position towards the revolving force that axis L2 and axis L1 is roughly coaxial tilt from the pre-Angle Position that engages.Coupling 150 and driving shaft 180 are engaged with each other (Figure 22 (d)).More specifically, recess 150z covers free end 180b.Like this, revolving force can stably be delivered to coupling 150 from driving shaft 180.In addition, now, pin 152 is positioned at opening 150g (Fig. 6 (b)), and pin 182 is positioned at intake section 150k.
In this embodiment, when coupling 150 starts to engage with driving shaft 180, driving shaft 180 have rotated.Therefore, coupling 150 starts to rotate immediately.But, when coupling 150 engage with driving shaft 180, driving shaft 180 motionless time, coupling 150 is awaited orders with rotatable state, and at this moment pin 182 is positioned at intake section 150k.
As mentioned before, according to this embodiment, coupling 150 can pivotable relative to axis L1.Therefore, tilted by coupling 150 itself, coupling 150 can correspond to rotary body C rotation when interfering driving shaft 180 (coupling) engages with driving shaft 180.
In addition, the phase differential no matter between driving shaft 180 and coupling 150 how, all can carry out the bonding operation of above-mentioned coupling 150.See Figure 14 and Figure 23, the phase differential between coupling and driving shaft will be described.Figure 23 illustrates the phase place of coupling and driving shaft.In Figure 23 (a), the driving shaft receiving surface 150f of pin 182 and coupling 150 the sense of rotation X4 relative to rotary body upstream end toward each other.In Figure 23 (b), the projection 150d of pin 182 and coupling 150 toward each other.In Figure 23 (c), the free end 180b of driving shaft and the projection 150d of coupling 150 toward each other.In Figure 23 (d), the receiving surface 150f of free end 180b and coupling toward each other.As shown in figure 14, coupling 150 be mounted to relative to development axle 153 in all directions all can pivotable.Therefore, as shown in figure 23, no matter development axle 153 relative to sense of rotation X4 phase place how, coupling 150 all can along sense of rotation X4 pivotable.In addition, the phase differential no matter between driving shaft 180 and coupling 150 is how, on sense of rotation X4, the position of free end position, downstream 150A1 than driving shaft free end 180b3 closer to developer roll 110 side.In addition, the pitch angle of coupling 150 is set as making: on sense of rotation X4, free end position, upstream 150A2 than driving shaft free end 180b3 closer to pin 182 side.By means of this setting, free end position, the downstream 150A1 along sense of rotation X4 passes through from driving shaft free end 180b3 side in response to the rotation process of rotary body C.Further, when Figure 23 (a), driving shaft receiving surface 150f contact plug 182.When Figure 23 (b), projection 150d contact plug 182.When Figure 23 (c), projection 150d contacts free end 180b.When Figure 23 (d), receiving surface 150f contacts free end 180b.In addition, contact force (loading force) close with the axis L1 parallel position of axis L2 owing to producing when rotary body C rotates, and they are engaged with each other (being coupled).Therefore, how are the phase differential no matter between driving shaft 180 and coupling 150 or the phase differential between coupling 150 and development axle 153, and they all can be engaged with each other.
See Figure 24, by the revolving force transmission operation described under developer roll 110 rotational case.Driving shaft 180 rotates along the X8 direction in figure together with gear (spiral gear) 181 because being received from the revolving force of motor 64.Further, any one in the revolving force receiving surface 150e1 to 150e4 of coupling 150 is contacted with the pin 182 of driving shaft 180 one.Like this, coupling 150 rotates.Coupling 150 further rotates.Like this, the revolving force of coupling 150 transmits surperficial 150h1 or 150h2 and contacts the pin 155 with development axle 153 one.Then, the revolving force of driving shaft 180 makes developer roll 110 rotate by coupling 150 and development axle 153.
In addition, the free end 153b of development axle 153 contacts receiving surface 150i.The free end 180b of driving shaft 180 contacts receiving surface 150f.Like this, coupling 150 is correctly located (Figure 22 d).More specifically, coupling 150 covers free end 180 by recess 150z and navigates to driving shaft 180.Now, even if some is not coaxial slightly each other for axis L3 and axis L1, coupling 150 also can rotate, and will apply large load to development axle 153 and driving shaft 180 because of the little inclination of coupling 150.Therefore, even if offset because rotary body C rotates the position causing Delevoping cartridge B to produce slightly, and then driving shaft 180 departs from each other with development axle 153, and coupling 150 also can transmit revolving force reposefully.
This is one of remarkable result of embodiment according to coupling of the present invention.
See Figure 25, leave the movement of precalculated position (developing location) by describing in response to Delevoping cartridge B is rotated along one direction by rotary body C, the operation that coupling 150 and driving shaft 180 depart from.
First, the position of each pin 182 when Delevoping cartridge (B) moves apart precalculated position will be described.After imaging completes, as apparent from the foregoing description, pin 182 is positioned at any two places (Fig. 6) entered or in intake section 150k1 to 150k4.Further, pin 155 is positioned in opening 150g1 or 150g2.
Below by describe with utilize Delevoping cartridge complete imaging operation after be switched to the operation that the operation of next Delevoping cartridge B is associated, coupling 150 and driving shaft 180 depart from.
Under the state that the rotation of development axle 153 stops, the axis L2 of coupling 150 is roughly coaxial relative to axis L1 (revolving force transmission Angle Position).Development axle 153 moves along disassembly direction X6 with Delevoping cartridge (B) together with, and (Figure 25 a) to be positioned at the free end 180b of the receiving surface 150f of upstream or projection 150d contact driving shaft 180 or pin 182 relative to the sense of rotation of rotary body.Axis L2 starts towards the upstream oblique (Figure 25 (b)) relative to sense of rotation X4.For development axle 153, the vergence direction of the coupling 150 when this vergence direction and coupling 150 engages drive shaft 180 is contrary.By the rotation process of rotary body C, coupling 150 moves, and keeps contacting with free end 180b relative to the upstream free end 150A2 of sense of rotation X4 simultaneously.Along axis L2, upstream free end 150A2 tilts (Figure 25 (c)) to the free end 180b3 of driving shaft.In this state, coupling 150 passes through (Figure 25 (d)) when contacting with free end 180b3 from driving shaft 180 side.
Therefore, coupling 150 transmits Angle Position from revolving force and moves on to disengaging Angle Position, and the part (upstream free end 150A2) being positioned at driving shaft 180 upstream relative to sense of rotation X4 of coupling 150 can be walked around from driving shaft 180 side.Therefore, Delevoping cartridge B moves on to the position shown in Figure 21 by the rotation of rotary body C.In addition, before rotary body C completes a turn over, coupling 150 (axis L1) tilts towards the downstream relative to sense of rotation X4 by means of unshowned device.In other words, coupling 150 moves on to from disengaging Angle Position and engages Angle Position in advance.Like this, after rotary body C completes one turn over, under coupling 150 is in the state that can engage with driving shaft 180.
As from the foregoing description can clearly, the pre-joint Angle Position of coupling 150 be larger relative to the angle of axis L1 than departing from Angle Position relative to the angle of axis L1.Angle Position is engaged in advance this is because preferably preset, make in the bonding operation process of coupling, relatively grow (Figure 22 b) relative to the distance between the downstream free end position 150A1 of sense of rotation X4 and the free end 180b3 of driving shaft.This considers that the dimensional tolerence of parts designs.On the contrary, when coupling departs from, the rotation of axis L2 and rotary body C is tilted explicitly.Therefore, the downstream free end 150A2 of coupling 150 moves along the free end 180b3 of driving shaft.In other words, on the direction of axis L1, (Figure 25 (c)) is roughly in alignment with each other relative to the downstream free end position 150A2 of sense of rotation X4 and free end 180b3.In addition, when coupling 150 departs from driving shaft 180, how all can depart from regardless of the phase differential between coupling 150 and pin 182.
As shown in figure 22, Angle Position is transmitted at the revolving force of coupling 150, coupling 150 makes the state in precalculated position (position relative with photosensitive drums) being installed on equipment master component (A) at Delevoping cartridge (B) relative to the angle of axis L1 under, coupling 150 receives the revolving force transmission from driving shaft 180, and it rotates.
In addition, the pre-joint Angle Position of coupling 150 refers to that coupling 150 is installed in the install operation process in precalculated position according to being rotated in of rotary body C, the Angle Position before will engaging with driving shaft 180.
In addition, the disengaging Angle Position of coupling 150 refers to and moves apart in the process in precalculated position according to the Delevoping cartridge B that is rotated in of rotary body C, and when Delevoping cartridge (B) departs from driving shaft 180, coupling 150 is relative to the Angle Position of axis L1.
Engage Angle Position pre-or depart from Angle Position, the angle β 1 that the angle β 2 that axis L2 and axis L1 is formed and β 3 is formed at revolving force transmission Angle Position than axis L2 and axis L1 is large.Preferred as angle β 1,0 degree.But, in this embodiment, if angle β 1 is less than about 15 degree, the smooth transfer of revolving force can be realized.This is also one of effect of this embodiment.The scope spent as angle β 2 and β 3, about 20 to 60 is preferred.
As mentioned before, coupling is pivotally installed on axis L1.Further, coupling 150 tilts according to the rotation of rotary body C, and can not interfere driving shaft.
At this, according to above-mentioned embodiment of the present invention, even if Delevoping cartridge B (developer roll 110) move in response to rotary body C moves along the one direction in axis L3 direction being approximately perpendicular to driving shaft 180, drum coupling member 150 also can complete and being coupled (joint) and disengaging relative to driving shaft 180.Transmit Angle Position, pre-joint Angle Position this is because revolving force can be according to the bulging coupling member 150 of embodiment of the present invention and departs from Angle Position.
At this, as previously described, revolving force transmits the Angle Position for the revolving force making developer roll 110 rotate being delivered to developer roll 110 that Angle Position refers to bulging coupling member 150.
Pre-joint Angle Position is the position of transmitting Angle Position inclination from revolving force, and it is the Angle Position before drum coupling member 150 engages with revolving force applying portion of drum coupling member 150.
Depart from Angle Position and refer to that transmitting Angle Position from revolving force tilts away from the pre-position engaging Angle Position, and be the Angle Position for making drum coupling member 150 depart from driving shaft 180 of drum coupling member 150.
In the foregoing description, when departing from, with the rotation of rotary body C explicitly, upstream receiving surface 150f or upstream projection 150d contacts the free end 180b of driving shaft 180.Like this, the upstream oblique of axis L2 towards sense of rotation X4 has been described.But in this embodiment, this is not necessary.Such as, toggle joint type spring (resilient material) is set in the pivot point vicinity of coupling.This structure makes when coupling engages, and produces the loading force towards sense of rotation X4 downstream relative to coupling.When coupling departs from, corresponding with the rotation of rotary body C, due to the function of this two-phase loaded type spring, contrary with joint situation, the loading force towards sense of rotation X4 upstream is produced to coupling.Therefore, when coupling departs from, do not contact with each other along the upstream receiving surface 150f or projection 150d of sense of rotation X4 and the free end 180b of driving shaft 180, and coupling and driving shaft depart from.In other words, as long as the axis L2 of coupling 150 tilts in response to the rotation of rotary body C, any means are all available.In addition, before coupling 150 will engage with driving shaft 180, coupling will tilt, and make the secondary part 150a of coupling face the downstream of sense of rotation X4.In other words, under coupling is placed in the pre-state engaging Angle Position in advance.Therefore, embodiment 2 and any means below in embodiment are all available.
At this, see Figure 26, the measure being reduced to picture (development) required time will be described in this embodiment.Figure 26 is the sequential chart of the rotation that developer roll etc. is shown.
At this, see Figure 26, in this embodiment description is reduced to the measure of picture (development) required time.Figure 26 is the sequential chart of the rotation for illustrating developer roll etc.
In fig. 26, illustrate from developing apparatus (Delevoping cartridge) and be positioned at the state in original position until developer roll receives imaging commencing signal to realize the rotation of developer roll and the timing of stopping of the first color development (formation yellow image) and the second color development (formation magenta color image).For the follow-up development of the third and fourth color (form cyan image and form black image), omit diagram due to concise and to the point reason.
In this embodiment, as previously mentioned, the bonding operation between driving shaft 180 and coupling 150 completes in the rotary course of rotary body C, or just completes after the rotation of rotary body C stops.In the rotary course of rotary body C or just after the rotation of rotary body C stops, coupling 150 completes with the bonding operation of driving shaft 180.Then, developer roll 110 is in revolvable state, or rotates.
That is, when coupling 150 enter rotate with the drive axle 180 of the bonding operation of driving shaft 180, coupling 150 starts to rotate while engaging with driving shaft 180.Then, developer roll 110 starts to rotate.Further, when driving shaft 180 stops, coupling 150 stops, and can not rotate, even if be also like this when the joint of coupling 150 and driving shaft 180 completes.When driving shaft 180 starts to rotate, coupling 150 starts to rotate.Then, developer roll 110 starts to rotate.
In either case, according to this embodiment, master component sideway swivel force transmitting member (such as master component side coupling) does not need to move forward and backward in the axial direction.
In this embodiment, enter at coupling 150 and rotate with the drive axle 180 of the bonding operation of driving shaft 180.Therefore, imaging operation can start rapidly.Thus, compared with situation about stopping with driving shaft 180, the time required for imaging can reduce further.
Further, in this embodiment, under the rotation status of driving shaft 180, coupling 150 can be separated with driving shaft 180.
Therefore, in this embodiment, driving shaft 180 also can non rotating or stopping, engaging or depart to make coupling 150 with driving shaft.
That is, according to the coupling 150 in this embodiment, no matter driving shaft 180 rotates or stops, and coupling 150 all can engage with driving shaft 180 and depart from.This is also one of remarkable result of this embodiment.
Thereafter, sequentially carry out rotary body (developer roll) contact, form yellow image, rotary body (developer roll) is separated and developer roll rotates the step stopped.Start mutually side by side with the rotation of rotary body, the disengaging performing the coupling of Delevoping cartridge and the driving shaft of equipment master component operates, and thinks that the development operation of the second color is prepared.
That is, in this embodiment, the joint of coupling and disengaging operation can be carried out explicitly with the rotation of rotary body.Therefore, the time interval of the necessity between the first color development and the second color development can be shortened.Similarly, the time interval of the time interval and the 4th necessity between color development and original position of the time interval of the necessity between the second color development and the 3rd color development, the time interval of necessity between the 3rd color development and the 4th color development, the necessity between original position and the first color development also can reduce.Therefore, the time obtained on sheet material needed for coloured image can be reduced.This is also one of remarkable result of this embodiment.
See Figure 27 and Figure 28, a modified example of development axle will be described.Figure 27 is the stereographic map of axial component of developing.Figure 28 illustrates the characteristic in Figure 27.
In description above, the free end of development axle is spherical surface, the spherical surface of coupling contact development axle free end.But as Figure 27 (a) and 28 (a) illustrate, the free end 1153b of development axle 1153 can have plane.The marginal portion 1153c of the outer peripheral face of free end 1153b contacts coupling 150 to rotate coupling 150.Even if by means of this structure, axis L2 also can reliably pivotable relative to axis L1.In addition, do not need to process spherical surface.Therefore, it is possible to reduce costs.
In description above, another drives passing pin to be fixed to development axle.But as Figure 27 (b) and 28 (b) illustrate, it can be the component be separated with elongated development axle.First development axle 1253A is the component of the rubber part (not shown) for supporting developer roll.In addition, the second development axle 1253B and first develops the coaxial setting of axle 1253A, and rib 1253Bc is transmitted in the driving be provided with integratedly for engaging with coupling 150.In this case, by utilizing the integral type molding process such as injection mo(u)lding, geometric ranges can be increased.Therefore, rib part 1253Bc can expand.Therefore, the area of transmitting portions 1253Bd is driven to increase.Even if it is the development axle be made up of resin material, it also can reliably transmitting torque.In the drawings, when coupling 150 rotates along X8 direction, the driving transmitting portions 1253Bd that surperficial 150h contacts the second driving shaft is transmitted in the driving of coupling.When now contact area is more roomy, the stress be applied on rib 1253Bc is just less.Therefore, the probability of damage of coupling etc. just reduces.In addition, the first development axle can be common metal shaft, and the second development axle can be the integrally moulded product that resin material is formed.In this case, cost can be realized reduce.
As shown in Figure 27 (c) He 28 (c), opposed end 1355a1,1355a2 of revolving force passing pin (revolving force receiving unit) 1355 are fixedly entered in driving transfer hole 1350g1 or 1350g2 of coupling 1350 in advance by press fit etc.Thereafter, the development axle 1353 that free end 1353c1,1353c2 are formed as slot form can be inserted.Now, preferably, the bonding part 1355b of the free end (not shown) relative to development axle 1353 of pin 1355 is formed as spherical form, makes coupling 1350 energy pivotable.By fixed pin 1355 in advance in this way, the size of the stand-by hole 1350g of coupling 1350 or else need not be increased necessarily.Therefore, the rigidity of coupling enhances.
In addition, in description above, the inclination of the axis of coupling is carried out along development axle free end.But as Figure 27 (d), 27 (e) and 28 (d) illustrate, this inclination can be carried out along the surface in contact 1457a of the supporting member 1457 coaxial with development axle 1453.In this case, the free end surface 1453b of development axle 1453 is positioned in the level suitable with the end face of supporting member.Further, the inside of the opening 1450g of coupling 1450 is inserted from revolving force passing pin (revolving force receiving unit) 1453c that free end surface 1453b is outstanding.Revolving force transmits by transmitting surface this pin 1453c of contacting of (revolving force transmitting portions) 1450h with the revolving force of coupling.In this way, when coupling 1450 tilts, surface in contact 1457a is arranged on supporting member 1457.Like this, just need not directly process development axle, and can cut down finished cost.
In addition, similarly, the spherical surface of free end can be the molded resin parts as separating member.In this case, the processing cost of axle can be reduced.This is because waited the structure of the axle of processing to simplify by cutting.In addition, the variable range of the spherical surface of axle free end is narrow, and by limiting the scope needing high precision to process, can cut down finished cost.
See Figure 29, the modified example of driving shaft will be described.Figure 29 is the stereographic map of driving shaft and developing drive gear.
Similar with development axle, the free end of driving shaft 1180 can be formed as flat surfaces 1180b, as shown in Figure 29 (a).Like this, the simple structure of axle, and can cut down finished cost.Pin (revolving force applying portion) is indicated by reference number 1182.
In addition, similar with development axle, drive transmitting portions 1280c1,1280c2 can be molded integratedly, as shown in Figure 29 (b) with driving shaft 1280.When driving shaft is molded resin parts, transmitting portions is driven to be integrally molded parts.Therefore, cost can be realized reduce.
As shown in Figure 29 (c), in order to the scope of the free end 1380b making driving shaft 1380 narrows, the external diameter of axle free end 1380c can reduce compared with the external diameter of main part 1380a.Free end 1380b claimed accuracy, to determine the position of coupling (not shown) as described above.Therefore, by sphere being restricted to the contact portion only contacted with coupling, can reducing and require high-precision surface.Like this, can cut down finished cost.In addition, the unnecessary free end of spherical surface can be cut similarly.
In addition, in the foregoing embodiment, between developer roll and equipment master component, there is not play along axis L1 direction.At this, by the localization method of developer roll described when to there is play along axis L1 direction.In other words, coupling 1550 is provided with conical surface 1550e, 1550h.As for driving shaft, by rotating the power produced along pushing direction.Like this, coupling and development axle are located relative to the direction of axis L1.See Figure 30 and Figure 31, will describe in detail.Figure 30 is coupling stereographic map alone and vertical view.Figure 31 is the exploded perspective view of driving shaft, development axle and coupling.
As shown in Figure 30 (b), revolving force receiving surface 1550e forms angle α 5 relative to axis L2.When driving shaft 180 rotates along T1 direction, pin 182 and receiving surface 1550e contact with each other.Then, component is applied to coupling 1550 along T2 direction, and coupling moves along T2 direction.In more detail, coupling 1550 moves, and (Figure 31 a) contacts the free end 180b of driving shaft 180 until the driving shaft receiving surface 1550f of coupling 1550.Like this, the position relative to axis L2 direction of coupling 1550 is just determined.In addition, free end 180b is spherical surface, and the driving shaft receiving surface 1550f of coupling 1550 is conical surfaces.Therefore, the position of secondary part 1550a relative to driving shaft 180 of coupling 1550 is determined along the direction perpendicular to axis L2.
In addition, as shown in Figure 30 (c), revolving force transmits surface (revolving force transmitting portions) 1550h and forms angle α 6 relative to axis L2.When coupling 1550 rotates along T1 direction, transmit surperficial 1550h and pin 155 contacts with each other.Then, component is applied to pin 155 along T2 direction, and pin moves along T2 direction.Further, development axle 153 moves, until the free end 153b of development axle 153 contacts the development area supported 1550i (Figure 31 b) of coupling 1550.Like this, the position of development axle 153 (developer roll) relative to axis L2 direction is determined.
In addition, the development area supported 1550i of coupling 1550 is conical surfaces, and the free end 153b of development axle 153 is spherical surfaces.Therefore, along the direction of vertical axis L2, determine the position of drive part 1550b relative to development axle 153 of coupling 1550.
Select bevel angle α 5 and α 6, to make to be enough to produce the power moving coupling and developer roll along pushing direction.Further, different according to load, angle can change.But if be provided with other device for determining pushing direction position, then bevel angle α 5 and α 6 can be less.
Therefore, as mentioned before, coupling is provided with the sloping portion for generation of the power that draws in along axis L2 direction, and is provided with for determining along the trochoidal surface perpendicular to the position in the direction of axis L2.Like this, coupling the position along axis L2 direction and can side by side determine along perpendicular to the position in the direction of this axis.In addition, reliable revolving force transmission can be realized further.To be described below.When the revolving force receiving surface of coupling or revolving force transmission surface do not arrange aforesaid pitch angle, the revolving force transmission surface of coupling or revolving force receiving surface can tilt due to factors such as the impacts of dimensional tolerence, and produce component along the direction (direction contrary with the T2 of Figure 30) of axis L2.Like this, the contact between the revolving force receiving surface driving passing pin and coupling and revolving force transmission surface is just disturbed.But, by means of said structure, this problem can be avoided.
But coupling not only must arrange this sloping portion drawn in but also the trochoidal surface being provided with location.Such as, replacing the sloping portion being used for pulling along axis L2 direction, the parts for exerting a force along axis L2 direction can being added.From now on, only otherwise particularly point out, the situation being not only formed with inclined surface but also being formed with trochoidal surface will be described.
See Figure 32, use description to adjust the vergence direction of coupling for the device engaged between coupling and the driving shaft of equipment master component relative to Delevoping cartridge.Figure 32 is the side view of the critical piece of the driving side that Delevoping cartridge is shown, Figure 33 be along Figure 32 S7-S7 crossed by cut-open view.
At this, in order to adjust the vergence direction of coupling 150 relative to Delevoping cartridge B, supporting member (installation component) 1557 is provided with adjustment member 1557h1 or 1557h2.This adjustment member 1557h1 or 1557h2 is arranged so that: before coupling will engage with driving shaft 180, adjustment member 1557h1 or 1557h2 will become almost parallel with sense of rotation X4.In addition, the interval D 7 of adjustment member 1557h1 or 1557h2 is more bigger than the external diameter Φ D6 of the drive part 150b of coupling 150.Like this, coupling 150 can along sense of rotation X4 pivotable.In addition, coupling can along all directions pivotable relative to development axle.Therefore, no matter which kind of phase place development axle is in, and coupling can tilt along controlled direction.Therefore, easily more reliably driving shaft (not shown) is inserted being used in the insertion opening 150m of driving shaft of coupling 150.Therefore, they can engage more reliably.
In addition, in description above, the pre-joint Angle Position of coupling 150 departs from the angle large (Figure 22, Figure 25) of Angle Position relative to axis L1 relative to the angle ratio of axis L1.But this is optional.To be described see Figure 34.
Figure 34 is the longitudinal sectional view of the installation process that coupling is shown.As shown in figure 35, under (a) state of the installation process of coupling, on the direction of axis L1, relative to free end position, the downstream 1850A1 of sense of rotation X4 than driving shaft free end 180b3 closer to drive pin 182 (revolving force applying portion).Under (b) state, free end position 1850A1 contacts free end 180b.Now, the free end 180b that free end position 1850A1 is in the driving shaft 180 in downstream along the sense of rotation X4 relative to rotary body C moves towards development axle 153.Further, free end position 1850A1 is in this position from the free end 180b3 side process of driving shaft 180, and coupling 150 enters and engages Angle Position (Figure 34 (c)) in advance.Finally, the joint ((revolving force transmission Angle Position) Figure 34 (d)) between coupling 1850 and driving shaft 180 is set up.As free end portion 1850A1 from free end 180b3 side through out-of-date, free end position 1850A1 contacts free end 180b3, or is positioned at development axle 153 side or developer roll side.
The example of this embodiment will be described below.
First, as shown in Figure 5, the diameter of axle of development axle 153 is Φ Z1, and the diameter of axle of pin 155 is Φ Z2, and length is Z3.As shown in Fig. 6 (d), (e) and (f), the maximum outside diameter of the secondary part 150a of coupling 150 is Φ Z4, the diameter forming the imaginary circle C1 (Fig. 6 (d)) of the inner end of projection 150d1 or 150d2 or 150d3 or 150d4 is Φ Z5, and the maximum outside diameter of drive part 150b is Φ Z6.See Figure 22 and 25, the angle formed between coupling 150 and conical driving shaft receiving surface 150f is α 2, and the angle formed between coupling 150 and axle receiving surface 150i is α 1.The diameter of axle of driving shaft 180 is Φ Z7, and the diameter of axle of pin 182 is Φ Z8, and length is Z9.In addition, what revolving force transmitted Angle Position is β 1 relative to the angle of axis L1, and the pre-angle engaging Angle Position is β 2, and the angle departing from Angle Position is β 3.In such examples:
Z1=8mm; Z2=2mm; Z3=12mm; Z4=15mm; Z5=10mm; Z6=19mm; Z7=8mm; Z8=2mm; Z9=14mm; α 1=70 degree; α 2=120 degree; β 1=0 degree; β 2=35 degree; β 3=30 degree.
Confirmed by means of above-mentioned setting, the device of this embodiment can work satisfactorily.But these settings do not limit the present invention.
[embodiment 2]
See Figure 36 to Figure 38, description is applied the second embodiment of the present invention.
A kind of device of axis of the axis inclination coupling relative to developer roll will be described in this embodiment.
In the description of the present embodiment, the reference number identical with embodiment 1 refers to the element with corresponding function in the present embodiment, and omits its detailed description for simplicity.This is also applicable to other embodiment hereinafter described.
Figure 36 is the stereographic map that the coupling locking component (this is that present embodiment is specific) be pasted onto on supporting member is shown.Figure 37 is the amplification stereogram of the critical piece of the driving side of Delevoping cartridge.Figure 38 is stereographic map and longitudinal sectional view that engagement state between driving shaft and coupling is shown.
As shown in figure 36, supporting member 3157 has the space 3157b around a coupling part.As retaining member for keep coupling 3150 tilt coupling locking component 3159 be pasted onto form described space cylindrical surface 3157i on.As hereinafter by description, this locking component 3159 is the components for temporarily maintaining the state that axis L2 tilts relative to axis L1.In other words, as shown in figure 36, the flange portion 3150j of coupling 3150 contacts this locking component 3159.Like this, axis L2 maintains the state tilted towards the downstream of Delevoping cartridge sense of rotation (X4) relative to axis L1.Therefore, as shown in figure 36, locking component 3159 is arranged on the surface of the upstream cylinder shape relative to the sense of rotation X4 3157i of supporting member 3157.As the material of locking component 3159, the material with relatively great friction coefficient of such as rubber and ameripol, or the resilient material of such as sponge and leaf spring are all suitable.This is because the inclination of axis L2 can be maintained by means of friction force, elastic force etc.
See Figure 38, use description to the bonding operation (part for the installation and removal operation of Delevoping cartridge) that coupling 3150 and driving shaft 180 are engaged.Figure 38 (a1) and (b1) illustrate the state before will engaging, and Figure 38 (a2) and (b2) illustrate the state after having engaged.
As shown in Figure 38 (a1) and Figure 38 (b1), the axis L2 of coupling 3150 tilts (in advance engage Angle Position) relative to axis L1 towards the downstream (retrieving position) of sense of rotation X4 by the power of locking component 3159 in advance.By this inclination of coupling 3150, on axis L1 direction, the free end 3150A1 in (relative to installation direction) downstream than driving shaft free end 180b3 closer to Delevoping cartridge (developer roll) side.The free end 3150A2 of (relative to installation direction) upstream than the free end 180b3 of driving shaft 180 closer to pin 182.In addition, now, as mentioned before, the flange portion 3150j of coupling 3150 contacts locking component 3159.The heeling condition of axis L2 is maintained by the friction force of locking component 3159.
Thereafter, Delevoping cartridge B moves along sense of rotation X4.Like this, the driving shaft receiving surface 3150f of the free end contact coupling 3150 of free end surface 180b or pin 182.Further, due to its contact force (making the power that rotary body rotates), axis L2 is close to the direction parallel with axis L1.Now, flange portion 3150j separates with locking component 3159, and enters contactless state.
Finally, axis L1 and axis L2 roughly coaxially to each other.
Further, coupling 3150 is in wait (awaiting orders) state (Figure 38 (a2), (b2)) (the revolving force transmission Angle Position) that transmit revolving force.
Similar with embodiment 1, rotary body C around oscillation centre axis oscillating, and makes developer roll 110 contact photosensitive drums 107.Further, the revolving force of motor 64 is delivered to coupling 3150, pin 155, development axle 153 and developer roll 110 by driving shaft 180.In rotary course, axis L2 and axis L1 is roughly coaxial.Therefore, locking component 3159 does not contact coupling 3150, and does not affect the driving of coupling 3150.
After the imaging is complete, rotary body C swings along contrary direction, and developer roll 110 and photosensitive drums 107 separate.Then, in order to implement the imaging operation of next color, rotary body C starts to rotate.In this case, coupling 3150 and driving shaft 180 depart from.In other words, coupling 3150 transmits Angle Position from revolving force and moves to disengaging Angle Position.Due to identical with embodiment 1 (Figure 25) of operation in that case, therefore omit it for the sake of brevity and describe.
In addition, when executing a turn over to rotary body C, the axis L2 of coupling 3150 tilts by means of the downstream of unshowned device towards sense of rotation X4.In other words, coupling 3150 transmits Angle Position from disengaging Angle Position via revolving force and moves to and engage Angle Position in advance.By doing like this, flange portion 3150j contacts locking component 3159, and maintains the heeling condition of coupling again.
As mentioned before, the heeling condition of axis L2 is maintained by the locking component 3159 be pasted onto on supporting member 3157.Like this, the joint between coupling and driving shaft is just more reliably set up.
In the present embodiment, locking component 3159 is pasted onto side, the most upstream place relative to sense of rotation X4 of the inside surface 3157i of supporting member.But this is optional.Such as, it is required that the position of its heeling condition can be maintained when axis L2 tilts.
Described above is locking component 3159 to contact (Figure 38 (b1)) with flange portion (Figure 38 (b1)) 3150j.But contact position can be secondary part 3150a (Figure 38 (b1)).
In this embodiment, although having described locking component is separating member, this is optional.Such as, it can be molded (such as double color mold-making) integratedly with supporting member 3157, and the alternative locking component 3159 of supporting member 3157 directly contacts coupling 3150.Or, the surface of coupling can be made roughening in order to increase friction factor.
In addition, be pasted onto on development supporting member 3157 although described locking component 3159, locking component 3159 can be any object, as long as it is fixed on the component on Delevoping cartridge B.
[embodiment 3]
See Figure 39 to Figure 42, the 3rd embodiment of the present invention will be described.
Use description to the situation of the device relative to axis L1 tilt axis L2.
As shown in Figure 39 (stereographic map), specific to present embodiment, coupling pressing member is installed on supporting member.Figure 40 is the stereographic map that coupling pressing member is shown.Figure 41 is the amplification stereogram of the critical piece of the driving side of Delevoping cartridge.Figure 42 is stereographic map and the longitudinal sectional view of the bonding operation that coupling is shown.
As shown in figure 39, the inside surface 4157i of supporting member (installation component) 4157 is provided with spring support portions 4157e1,4157e2.In addition, coiler part 4159b, 4159c of helical torsion spring (coupling loaded members) 4159 are installed on support section 4157e1,4157e2.As shown in figure 40, the contact portion 4159a of loaded members 4159 contacts the secondary part 4150a side of the flange portion 4150j of coupling 4150.Spring 4159 distortion is to produce elastic force.Like this, the axis L2 of coupling 4150 tilts (Figure 41 engages Angle Position in advance) relative to axis L1.The contact position that loaded members 4159 contacts with flange portion 4150j is set in the downstream part relative to sense of rotation X4 at axle 153 center of developing.Therefore, axis (L2) tilts relative to axis (L1), makes secondary part 4150a side be directed to downstream relative to sense of rotation (X4).
In the present embodiment, although helical torsion spring is used as loaded members (resilient material), this is optional.Can produce any device of elastic force, such as sheet spring, rubber and sponge, be all available.But, in order to tilt axis L2, need a certain amount of stroke.Therefore, the component that described stroke can be provided is wished.
In addition, spring support portions 4157e1,4157e2 of supporting member 4157 and coiler part 4159b, 4159c play the effect of the holding rib for coupling described in conjunction with embodiment 1 (Fig. 9, Figure 12).
See Figure 42, the bonding operation (part for the rotation process of rotary body) between coupling 4150 and driving shaft 180 will be described.(a1) and (b1) in Figure 42 is the view before will engaging, and (a2) and (b2) in Figure 42 illustrates the state after having engaged.(a3) and (b3) in Figure 42 is the view engaging the state discharged, and (a4) and (b4) in Figure 42 is the view of the state that axis L2 tilts towards downstream relative to sense of rotation X4 again.
In the state (retreating position of coupling 4150) of Figure 42 (a1) and 42 (b1), the axis L2 of coupling 4150 relative to axis L1 in advance towards tilting (engaging Angle Position in advance) relative to the downstream of sense of rotation X4.Therefore, coupling 4150 tilts.Like this, on the direction of axis L1, relative to free end position, the downstream 4150A1 of sense of rotation X4 than driving shaft free end 180b3 closer to Delevoping cartridge (developer roll) side.In addition, relative to free end position, the upstream 4150A2 of sense of rotation X4 than driving shaft free end 180b3 closer to pin 182 side.In other words, as mentioned before, flange portion 4150j is pressed by loaded members 4159.Therefore, axis L2 tilts relative to axis L1 due to loading force.
Thereafter, Delevoping cartridge B moves along sense of rotation X4.Like this, the driving shaft receiving surface 4150f of the free end contact coupling 4150 of free end surface 180b or pin 182.Further, axis L2 is because contact force (making the power that rotary body rotates) is close to the angle parallel with axis L1.
Meanwhile, flange portion 4150j and loading spring 4159 contact with each other.Like this, spring 4159 distortion is to increase moment.Finally, axis L1 and axis L2 becomes roughly coaxial each other, and coupling 4150 is in rotational latency state (Figure 42 (a2), (b2)) (revolving force transmission Angle Position).
Similar with embodiment 1, revolving force is delivered to coupling 4150, pin 155, development axle 153 and developer roll 110 from motor 64 by driving shaft 180.The loading force of loaded members 4159 is applied to coupling 4150 when rotated.But if the driving torque of motor 64 has enough allowances, then coupling 4150 will with high-precision rotary.
When rotary body further rotates, coupling 4150 will be separated with driving shaft 180, as Figure 42 (a3) and (b3) illustrate.In other words, the free end spherical surface 180b of driving shaft 180 pushes the driving shaft receiving surface 4150f of coupling.Like this, axis L2 is relative to axis L1 (reverse direction of sense of rotation X4) inclination (disengaging Angle Position) in the opposite direction.By doing like this, loaded members 4159 distortion further, makes loading force (elastic force) increase further.Therefore, after coupling 4150 departs from driving shaft 180, axis L2 due to loaded members 4159 loading force again relative to axis L1 along sense of rotation X4 inclination (engaging Angle Position in advance, Figure 42 (a4), (b4)).Like this, even if arrange not special and be used for making when driving shaft 180 and coupling 4150 are coupled again each other by the rotation of rotary body C axis L2 towards the pre-device engaging Angle Position and tilt, driving shaft 180 and coupling 4150 also can be connected to each other (can engage).
As previously described, can realize loading by the loaded members 4159 be arranged on supporting member 4157.Like this, axis L2 tilts relative to axis L1.Therefore, reliably can maintain the heeling condition of coupling 4150, and guarantee the joint (being coupled) between coupling 4150 and driving shaft 180.
The position of the loaded members in this embodiment is not restricted.Such as, it can be the another location on supporting member 4157, can be maybe the component being different from this component.
In addition, the loading direction of loaded members 4159 is identical with the direction of axis L1, but it can be any direction, as long as axis L2 tilts along predetermined direction.
In addition, the force application location of loaded members 4159 is positions of flange portion 4150j, but it can be any position of coupling, as long as axis L2 tilts along predetermined direction.
[embodiment 4]
See Figure 43 to Figure 46, the 4th embodiment of the present invention will be described.
Use description to the device relative to axis L1 tilt axis L2.
Figure 43 is the exploded perspective view of state before the main member assembling that Delevoping cartridge is shown.Figure 44 is the enlarged side view of the driving side of Delevoping cartridge.Figure 45 is the longitudinal sectional view schematically showing the structure that axis L2 is tilted.Figure 46 is the longitudinal sectional view of the bonding operation illustrated between driving shaft and coupling.
As shown in Figure 43 and Figure 45, supporting member (installation component) 5157 is provided with coupling locking component 5157k.When supporting member 5157 is assembled along axis L1 direction, when the inclined surface 5150m of the part contact coupling 5150 of the locking surface 5157k1 of locking component 5157k, a described part engages with the upper surface 5150j of flange portion 5150j.Now, flange portion 5150j installs in the mode that there is play (angle α 49) between locking surface 5157k1 and the cylindrical part 153a of development axle 153.Even if when the dimensional tolerence of coupling 5150, supporting member 5157 and development axle 153 changes, owing to arranging this play (angle α 49), flange portion 5150j1 also reliably can lock onto the lock part 5157k1 of supporting member 5157.
As shown in Figure 45 (a), axis L2 tilts, and makes secondary part 5150a side face the downstream of sense of rotation X4 relative to axis L1.In addition, because flange portion 5150j is all circumferentially extending, it all can be installed therefore to be in which kind of phase place regardless of coupling 5150.In addition, as in conjunction with described by embodiment 1, coupling can along sense of rotation X4 pivotable by means of adjustment member 5157h1 or 5157h2.In addition, in this embodiment, locking component 5157k is arranged on the position, most downstream relative to sense of rotation X4.
As mentioned below, as shown in Figure 45 (b), under the state engaged with driving shaft 180, flange portion 5150j discharges from locking component 5157k.In addition, coupling 5150 no longer retrains by locking component 5157k.When assembling supporting member 5157, when coupling 5150 can not maintain heeling condition, by the drive part 5150b (direction of the arrow X14 of Figure 45 (b)) of the pushing couplings such as instrument.Like this, coupling 5150 will easily be installed (Figure 45 (a)).
See Figure 46, the bonding operation (part for the rotation process of rotary body) between coupling 5150 and driving shaft 180 will be described.Figure 46 (a) illustrates that the view before will engaging, Figure 46 (b) are the view of a part after driving shaft 180 of coupling 5150.In addition, what Figure 46 (c) illustrated coupling 5150 is tilted through the state that driving shaft 180 is released, and Figure 46 (d) illustrates the state after joint.
Under the state of Figure 46 (a) with (b), coupling 5150 is in retreating position, tilts (engaging Angle Position in advance) at the axis L2 of this position coupling 5150 in advance relative to axis L1 to sense of rotation X4.By the inclination of coupling 5150, be in than the position of driving shaft free end 180b3 closer to Delevoping cartridge B (developer roll) relative to free end position, the downstream 5150A1 of sense of rotation X4.In addition, relative to free end position, the upstream 5150A2 of sense of rotation X4 than driving shaft free end 180b3 closer to pin 182 side.Now, as previously described, flange portion 5150j contacts the locking surface 5157k1 of locking component 5157k, maintains the heeling condition of coupling.
Thereafter, as shown in Figure 46 (c), Delevoping cartridge B moves along sense of rotation X4.Like this, the taper driving shaft receiving surface 5150f of the coupling 5150 or free end 180b of driven protuberance 5150d contact driving shaft 180 or pin 182.Due to the power produced because of contact, flange portion 5150j is separated with locking surface 5157k1.Like this, the locking of coupling 5150 relative to supporting member 5157 is just released.Further, in response to the rotation of rotary body C, coupling tilts, and makes axis L2 parallel with axis L1 gradually.At flange portion 5150j by afterwards, locking component 5157k gets back to front position due to restoring force.Then, coupling 5150 no longer retrains by locking component 5157k.Finally, as shown in Figure 46 (d), axis L1 and axis L2 becomes roughly coaxial, and sets up rotational latency state (revolving force transmission Angle Position).
After imaging operation completes, next Delevoping cartridge B arrives developing location.For this purpose, rotary body C rotates again.In this case, coupling 5150 and driving shaft 180 depart from.In other words, coupling 5150 transmits Angle Position from revolving force and moves to disengaging Angle Position.Due to identical with embodiment 1 (Figure 25) of details of operation in this case, therefore omit it for the sake of brevity and describe.
In addition, when completing a turn over to rotary body C, the axis L2 of coupling 5150 tilts by means of the downstream of unshowned device towards sense of rotation X4.In other words, coupling 5150 transmits Angle Position from disengaging Angle Position via revolving force and moves to and engage Angle Position in advance.By doing like this, flange portion 5150j contacts locking component 5157k, and again maintains the heeling condition of coupling.
As previously described, the vergence direction of coupling 5150 is adjusted by the lock part 5157k of supporting member 5157.Like this, the heeling condition of coupling 5150 can more reliably be maintained.Further, the joint between coupling 5150 and driving shaft 180 is reliably formed.In addition, when rotated, the structure that locking component 5157k does not contact coupling 5150 also contributes to the stable delivery of revolving force.
In this embodiment, locking component 5157k has elastic part.But locking component 5157k can not have elastic part, and it can be formed as the shape of rib, and by it, the flange portion of coupling is out of shape.Like this, similar effect is just provided.
In addition, locking component 5157k is arranged on the most downstream side place relative to sense of rotation X4.But locking component 5157k can be positioned at any position, as long as axis L2 can maintain the state tilting to predetermined direction.
In this embodiment, locking component 5157k is made up of a part for supporting member.But locking component 5157k can be arranged on the another location of supporting member, or it can be the component being different from supporting member.In addition, lock part can be separating member.
In addition, present embodiment, embodiment 2 or embodiment 3 can be implemented simultaneously, more reliably can complete coupling in this case relative to the joint of driving shaft and lock out operation.
[embodiment 5]
See Figure 47 to Figure 51, the 5th embodiment of the present invention will be described.
Be described to the device be used for relative to axis L1 tilt axis L2.
Figure 47 illustrates the supporting member of driving side and the view of rotary body flange observed along axis L1 direction.Figure 48 illustrates the view of the component of the equipment master component observed along axis L1 direction.Figure 49 and Figure 48 is identical, but with the addition of the track of coupling.Figure 50 be along Figure 49 line S10-S10, S11-S11, S12-S12, S13-S13, S14-S14 crossed by cut-open view.
First, see Figure 47, use description to the structure of the vergence direction adjusting coupling 150.Supporting member 7157 and rotary body C rotate integratedly.Supporting member 7157 is provided with for only allowing the adjustment member 7157h1 that coupling 7150 tilts along described one direction or 7157h2.Distance D6 between these adjustment member is more bigger than the external diameter (not shown) of the drive part 7150b of coupling 7150, rotates to allow coupling 7150.Adjustment member 7157h1 and 7157h2 to tilt an angle [alpha] 7 relative to sense of rotation X4.Like this, coupling 7150 can be pivoted to the X5 direction corresponding with α 7 relative to sense of rotation X4.
See Figure 48, use description to the method that coupling 7150 is tilted.In the present embodiment, the adjustment rib 1630R be fixed on driving shaft 180 is provided with.The radius of the inner surface in radial directions of rib 1630R from the R-2 of the upstream portion 1630Ra for sense of rotation X4 towards downstream part 1630Rb shorten gradually.Select the radius R-1 on this surface, make it contact the outer peripheral edges 7150c1 of the center section 7150c of coupling as shown in figure 50 and be interfered by it.
As coupling 7150 contact adjusting rib 1630R, coupling 7150 is pushed by the rotation towards rotary body C.Now, by adjustment member 7157h1 or 7157h2, adjust coupling 7150 in the direction of movement.Therefore, coupling 7150 tilts to X5 direction.
The increase of interference degrees also will increase the inclination of coupling 7150.The structure of adjustment rib 1630R made before coupling 7150 engages with driving shaft 180, and amount of interference increases always, until the pitch angle of coupling 7150 becomes pieceable angle gradually.In the present embodiment, be positioned at the position of the rotation same radius of distance rotary body C from position 1630Rb to the section of position 1630Rc.This radius is denoted as R-1.
Figure 49 illustrates when rotary body C rotates until the track that engages with driving shaft 180 along guide member 1630R of coupling 7150.Along the cross section crossed by the line S10-S10 to S14-S14 of Figure 49 shown in Figure 50 (a) to 50 (e).
Coupling 7150 enters the region of adjustment rib 1630R along X4 direction.Now, coupling faces the X6 direction being roughly working direction or the direction facing opposite direction X7 or face between X6 direction and X7 direction.At this, description coupling 7150 is faced the situation in X7 direction.
The vergence direction X5 (Figure 47) of coupling 7150 is relative to the angled α 7 of sense of rotation X4.Thus, when coupling 7150 tilts towards X7 direction, the secondary part 7150a of coupling is relative to the radially outward inclination (Figure 47) of rotary body C.Time in the scope that coupling 7150 enters adjustment rib 1630R, between coupling 7150 and adjustment rib 1630R, be provided with clearance G 1.
When the rotation of rotary body C proceeds to S11-S11 cross section, coupling 7150 and adjustment rib 1630R contact with each other (Figure 50 b).The radius of adjustment rib 1630R shortens gradually.Therefore, interference degrees along with before coupling 7150 so that increase.
In S12-S12 sectional position, adjustment rib 1630R upwards pushes coupling 7150, and it and development axle coaxial (Figure 50 c).Now, the movement of coupling 7150 is adjusted by adjustment rib 1630R.Thus, coupling 7150 only along X8 direction (in the cross-section location of S10-S10 only along X6 direction) pivotable, and can not can tilt towards the opposite direction of X8.
In xsect S13-S13 position, coupling adds relative to the interference degrees of adjustment rib 1630R.Thus, coupling 7150 is upwards pushed by rib 1630R, and is forced to tilt (Figure 50 (d)) (engaging Angle Position in advance) along X9 direction (be X8 direction in S12-S12 cross section).
In this state, rotary body C rotates, until coupling and driving shaft 180 coaxial (S14-S14 sectional position).Like this, coupling 7150 engages with driving shaft 180 (revolving force transmission Angle Position) by the operation similar with embodiment 1.
Thereafter, after the imaging is complete, coupling 7150 and driving shaft 180 depart from, thus complete sequence of operations (because this disengaging operation is identical with those in aforementioned embodiments, therefore for the sake of brevity omits it and describe).Each imaging all repeats this operation.
In order to make coupling interfere with each other with adjustment rib, therefore coupling from the contact outside relative to radial direction to adjustment rib, and makes coupling tilt.But, can be adjusted to and make the angle α 7 (along X5 direction in Figure 47) of adjustment member 7157h1 or 7157h2 symmetrical about tangential direction (X4 direction) line.Like this, when from radially inner side contact adjusting rib 1630R, same operation can be implemented.
Because the orientation of coupling 7150 adjusts by adjusting rib 1630R, therefore Delevoping cartridge does not need to be provided with the mechanism for the coupling that tilts.Like this, Delevoping cartridge cost can be realized reduce.
In this embodiment, by applying force to coupling by means of spring etc., coupling can reliably slide along rib.
In addition, coupling is moved in guide rib by the center section 7150c of coupling.But coupling moves in guide rib by the position being different from center section, as long as coupling can tilt.
In addition, present embodiment, embodiment 2 or embodiment 3 or embodiment 4 can side by side be implemented, and in this case, can guarantee the joint of coupling and depart from operation.
[embodiment 6]
See Figure 51 to Figure 52, the 6th embodiment of the present invention will be described.
In this embodiment, the structure of another coupling is adopted.
Figure 51 is the view of the coupling as main composition element of the present invention.Figure 52 is the longitudinal sectional view that the front state of the driving shaft of equipment master component and the engagement state of coupling and joint is shown.
First, see Figure 51, the structure of coupling itself will be described.Figure 51 (a) illustrates the view of the coupling observed from equipment master component side, Figure 51 (b) illustrates the view of the coupling observed from developer roll side, and Figure 51 (c) is along the cut-open view crossed by the S4-S4 in Figure 51 (a).
Coupling 8150 is general cylindrical shape.As shown in Figure 51 (c), coupling 8150 has driving shaft insertion opening part 8150m for receiving revolving force from the driving shaft of equipment master component and development axle insertion opening part 8150p.Opening 8150m is provided with taper driving shaft receiving surface 8150f.Drum type inner surface is provided with multiple driven protuberance 8150d (8150d1 or 8150d2 or 8150d3 or 8150d4) in rib form.In addition, in Figure 51 (a), revolving force transmit surface (revolving force receiving unit) 8150e1 to 8150e4 be arranged on projection 8150d relative to clockwise downstream part.Further, revolving force (driving force) contacts the transmission surface 8150e1 to 8150e4 of coupling 8150 by the pin 182 of driving shaft 180 and transmits.
Opening 8150p is provided with taper development area supported 8150i similarly.In addition, drum type inner surface is provided with rib 8150g1 or 8150g2.In addition, in Figure 50 (b), transmit surface (revolving force transmitting portions) 8150h1 or 8150h2 be arranged at the stand-by opening of developing drive 8150g1 or 8150g2 relative to clockwise upstream position.
See Figure 52, the bonding operation of coupling will be described.
Figure 52 (a) illustrates that development axle 8153 and coupling 8150 move the cut-open view of the state afterwards, before coupling 8150 engages with driving shaft 180 along sense of rotation X4.Axis L2 tilts to angle α 7, and making can through free end 180b relative to free end position, the downstream 8150A1 of sense of rotation X4.Now, the engagement state of the upstream 182a of pin 182 and transmission surface (revolving force receiving unit) 8150h1 or 8150h2 (Figure 51 c) of downstream 182b maintenance and coupling 8150.
Figure 52 (b) illustrate be positioned at Figure 52 (a) same orientation, in conjunction with the coupling 150 that embodiment 1 described.As can be understood from Figure 52 (b), similarly also inclined angle alpha 7 in axis L2 and Figure 52 (a) of coupling 150.Like this, drive to transmit between surperficial 150h1 relative to the upstream pin 155 of sense of rotation X4 and upstream and do not form joint.In other words, at pin 155 with transmit between surperficial 150h1 and there is clearance G 7.On the other hand, in the present embodiment, coupling 8150 is provided with the contact portion transmitted for revolving force at two positions, as shown in Figure 52 (a).Therefore, the orientation of coupling is stabilized further.
As previously described, coupling has cylindrical shape.Like this, even if the angle of inclination (engaging Angle Position in advance) of coupling must be increased, the contact portion transmitted for revolving force being positioned at two positions also can be guaranteed.Therefore, the tilt operation of stable coupling can be completed.
Because identical with embodiment 1 of the coaxial revolving force transmission between driving shaft 180 and development axle 153 and the joint releasing operation between driving shaft 180 and development axle 153, therefore omits those descriptions for simplicity.
[embodiment 7]
See Figure 53, the 7th embodiment of the present invention will be described.
Present embodiment is different from embodiment 1 in the structure of coupling.Figure 53 (a) is the stereographic map of the coupling with general cylindrical shape shape, and Figure 53 (b) is the cut-open view when the coupling being installed on Delevoping cartridge engages with driving shaft.
In Figure 53 (a) and 53 (b), revolving force is from the master component input being positioned at right side, and the developer roll being positioned at left side is driven.
The input side edge of coupling 9150 is provided with multiple driven protuberance (revolving force receiving unit) 9150d.In this embodiment, they are arranged on two positions.Entering part or intake section 9150k are arranged on to drive and receive between projection 9150d.Projection 9150d is provided with revolving force receiving surface (revolving force receiving unit) 9150e.The revolving force passing pin (revolving force applying portion) 9182 of driving shaft 9180 as described later contacts revolving force receiving surface 9150e.Like this, revolving force is just delivered to coupling 9150.
In order to stable delivery is to the torque of coupling, multiple revolving force receiving surface 9150e is preferably disposed on and samely circumferentially (is positioned on common circle).By configuring in this way, revolving force transmits constant-radius and stabilizes transmitted torque.The unexpected increase of torque can be avoided.In addition, from driving the angle transmitting stability, receiving surface 9150e is preferably disposed on the position of radially (180 degree) relatively.In addition, the quantity of receiving surface 9150e can be arbitrary, as long as the pin 9182 of driving shaft 9180 can be received by wait part 9150k.In this embodiment, described quantity is two.Revolving force receiving surface 9150e can not be positioned at circumferentially same, or they can not be arranged on position diametrically.
In addition, the cylindrical surface of coupling 9150 is provided with stand-by opening 9150g.In addition, opening 9150g is provided with revolving force and transmits surface (revolving force transmitting portions) 9150h.Development axle 9153 driving passing pin (revolving force receiving member) 9155 (Figure 53 (b)) contacts this revolving force and transmits surperficial 9150h.Like this, revolving force is delivered to developer roll 110 from master component A.
Similar to projection 9150d, revolving force transmission surface 9150h is preferably arranged on circumferentially same diametrically.
The structure (Figure 53 (b)) of development axle 9153 and driving shaft 9180 will be described below.In embodiment 1, cylindrical end is spherical surface.But in this embodiment, the diameter of the spherical free end 9153b of end is larger than the diameter of main part 9153a.By means of this structure, the left end end of coupling 9150 can situation of interfering have a down dip with main part 9153a.The structure of driving shaft 9180 is roughly the same with the structure of development axle 9153.In other words, the structure of free end 9180b is spherical surface, and its diameter is larger than the diameter of the main part 9180a that cylindrical part is formed.In addition, the pin (revolving force applying portion) 9182 of the approximate centre through the free end 9180b with spherical surface is set.Revolving force is delivered to transmission surface or the revolving force receiving surface 9150e of coupling 9150 by pin 9182.
Development axle 9153 and the spherical surface of driving shaft 9180 engage with the inside surface 9150p of coupling 9150.Like this, the relative position of development between axle 9153, coupling 9150 and driving shaft 9180 is just determined.For the sake of brevity coupling 9150, relative to the installation and removal operation of driving shaft 9180 and identical in embodiment 1, therefore omit it and describes.
As previously described, coupling has cylindrical shape, if therefore coupling closes with being coupling, then can determine relative to the position in the vertical direction in the axis L2 direction of coupling 9150.
The modified example of coupling will be further described.In the structure of the coupling 9250 shown in Figure 53 (c), cylindrical shape and coniform shape are brought together.Figure 53 (d) is the cut-open view of the coupling of this modified example.The secondary part 9250a (right side in figure) of coupling 9250 has cylindrical shape, and its inside surface 9250p engages with the spherical surface of driving shaft 9180.In addition, it has abutment surface 9250q, and can realize the location relative to axis between coupling 9250 and driving shaft 9180.Drive part 9250b has coniform shape (left side of figure), and similar to embodiment 1, is determined by the axle receiving surface 9250i that develops relative to the position of development axle 153.
The structure of the coupling 9350 shown in Figure 53 (e) is combinations of cylindrical shape and coniform shape.Figure 53 (f) is the cut-open view of this modified example.The secondary part 9350a of coupling 9350 has cylindrical shape (right side), and its inside surface 9350p engages with the spherical surface of driving shaft 9180.By the spherical surface 9180c of driving shaft 9180 is resisted against the cylindrical part with different-diameter divide between the marginal portion 9350q that formed, realize driving shaft 9180 location vertically.
The structure of the coupling 9450 shown in Figure 53 (g) is combinations of spherical surface, cylindrical shape and coniform shape.Figure 53 (h) is the cut-open view of this modified example, and wherein the secondary part 9450a (right side) of coupling 9450 has cylindrical shape, and its inside surface 9450p engages with the spherical surface 9450q of driving shaft.The spherical surface contact of driving shaft 180 is as the spherical surface 9450q of a spherical surface part.Like this, the position relative to axis L2 direction can just be determined.What be denoted as 9250d, 9350d and 9450d is all projections.What be denoted as 9250e, 9350e and 9450e is all revolving force receiving surface (revolving force receiving units).
[embodiment 8]
See Figure 54 to Figure 56, the 8th embodiment of the present invention will be described.
Present embodiment is different from embodiment 1 with the configuration aspects of coupling relative to the installation operation of driving shaft at coupling.Figure 54 is the stereographic map of the structure of the coupling 10150 that present embodiment is shown.The structure of coupling 10150 is combinations of cylindrical shape as described in embodiment 7 and coniform shape.In addition, conical surface 10150r is arranged in the free end side of coupling 10150.In addition, the surface being positioned at the opposition side of driving reception projection 10150d relative to axis L1 direction is provided with loading force receiving surface 10150s.
See Figure 55, the structure of coupling will be described.
The inside surface 10150p of the coupling 10150 and spherical surface 10153b of development axle 10153 is engaged with each other.Loaded members 10634 is inserted between the basal surface 10151b of previously described loading force receiving surface 10150s and development flange 10151.Like this, when rotary body C stops at precalculated position, coupling 10150 is loaded by towards driving shaft 180.In addition, similar to aforementioned embodiments, on flange portion 10150j, be adjacent to be provided with holding rib (not shown) relative to axis L1 direction and driving shaft 180.This prevents coupling 10150 to depart from from Delevoping cartridge.The inside surface 10150p of coupling 10150 is columniform.Therefore, coupling is can be installed on Delevoping cartridge B along the mode of axis L2 direction movement.
Figure 56 is the view in the orientation for illustrating coupling under coupling and driving shaft joint situation.Figure 56 (a) is the cut-open view of the coupling 150 of embodiment 1, and Figure 56 (c) is the cut-open view of the coupling 10150 of present embodiment.Figure 56 (b) is the cut-open view before the state arriving Figure 56 (c), and sense of rotation is illustrated by X4, and dot-and-dash line L5 is parallel to from the free end of driving shaft 180 line that installation direction paints.
In order to make coupling engage with driving shaft 180, need the free end 180b3 by driving shaft 180 relative to free end position, the downstream 10150A1 of sense of rotation X4.When embodiment 1, axis L2 is tilted beyond angle α 104.Like this, coupling moves to the position (Figure 56 (a) engages Angle Position in advance) that free end position 10150A1 does not interfere with free end 180b3.
On the other hand, in the coupling 10150 of present embodiment, under the state that it does not engage with driving shaft 180, the position that coupling 10150 enters closest to driving shaft 180 due to recovery (elasticity) power of loaded members (elastic component) 10634.In this state, when it moves along sense of rotation X4, part contact driving shaft (Figure 56 (b)) of the conical surface 10150r of coupling 10150.Now, power is applied to conical surface 10150r along direction X4, and therefore coupling 10150 due to the component of this power longitudinally X11 withdraw.The free end 10153b of development axle 10153 is resisted against the bearing part 10150t of coupling 10150.In addition, coupling 10150 deasil rotates (engaging Angle Position in advance) around the center P1 of the free end 10153b of development axle.Like this, free end position, the downstream 10150A1 relative to sense of rotation X4 of coupling from the free end 180b side of driving shaft 180 through (Figure 56 (c)).When driving shaft 180 and development axle 10153 become roughly coaxial, the driving shaft receiving surface 10150f of coupling 10150 contacts free end 180b due to the elastic force of loading spring 10634.Like this, coupling becomes and is in rotational latency state (Figure 55).Consider the amount of withdrawing of coupling 10150, the degree of tilt of axis L2 can be reduced to α 106 (Figure 56 (c)).
When after imaging operation completes, rotary body restarts to rotate along described one direction, free end 180b is crushed on due to the revolving force of rotary body on the driving shaft receiving surface 10150f of the conical by its shape of coupling 10150.Coupling 10150 is pivotable due to this power, and the direction (contrary with X11 direction) simultaneously due to this pivotable towards axis L2 withdraws.Coupling 10150 departs from driving shaft 180 (separation).
[embodiment 9]
See Figure 57, Figure 58 and Figure 59, embodiment 9 will be described.
Present embodiment the position (position of coupling) for inputting revolving force and the configuration aspects for revolving force to be delivered to developer roll and developer feeding roller from coupling different from embodiment 1.
Figure 57 is the stereographic map of Delevoping cartridge B.In addition, Figure 58 illustrates the stereographic map without the drive part of Delevoping cartridge B in side plate situation.Figure 59 (a) is the stereographic map of the driving input gear from driving side observation.Figure 59 (b) is the stereographic map of the driving input gear from non-drive side observation.
Developing gear 145 is arranged at a longitudinal end of developer roll 110.In addition, developer feeding roller gear 146 is arranged at a longitudinal end of developer feeding roller 115 (Fig. 1).Two gears are all fixed on roll shaft.Like this, coupling 150 is delivered to pin (revolving force receiving unit) 155 and gear 147 from the revolving force that equipment master component A receives.In addition, the revolving force received by gear 147 is delivered to developer roll 110 and developer feeding roller 115 by gear 145 and gear 146.Revolving force can be delivered to developer stirring member etc.In addition, can not be gear for transmitting the component of revolving force, and can be toothed belt etc.Such as the driving force such as gear or toothed belt transmission member can suitably use.
See Figure 59, the driving input gear 147 swingingly installing coupling 150 will be described.Gear shaft 11153 is fixed to the inner side of gear by press fit, bonding etc.The end 11153b of gear shaft 11153 has bulbous configuration, makes when axis L2 tilts that it can tilt reposefully.In this embodiment, although gear shaft 11153 is made of metal, it can be formed by resin material and gear 147.In addition, the revolving force passing pin (revolving force receiving unit) 155 for receiving revolving force from coupling 150 is arranged on the free end side of gear shaft 11153, and it is along extending with the direction of the axes transverse of gear shaft 11153.
Pin 155 is made of metal, and is fixed to gear shaft 11153 by press fit, bonding etc.The position of pin 155 can be satisfactory any position, as long as can carry out the transmission of revolving force.Preferably, pin 155 is through the spherical surface center of the free end 11153b of gear shaft 11153.This is because by means of this structure, even if there is deviation angle between gear shaft 11153 and axis L2, it is also always constant that revolving force transmits radius.Like this, the constant transmission of revolving force is just achieved.The quantity at revolving force transmission position can be any, and those skilled in the art can suitably select revolving force to transmit the quantity at position.But, in this embodiment, have employed single pin 155 from the angle of the transmission and assembling property of guaranteeing driving torque.Pin 155 is through the center of free end spherical surface 11153b.Like this, pin 155 is from the radially relative direction projection of the spherical surface of gear shaft 11153.In other words, revolving force transmits at two positions.At this, in this embodiment, although pin 155 is metals, it can be the product that the resin material be integrally formed with gear shaft 11153 and gear 147 is made.Gear 145,146 and 147 is spiral gears.
In addition, because the installation method of coupling 150 and embodiment 1 is identical, describe so omit it.
Gear 147 is provided with the space 147a for partly receiving coupling 150, and make when coupling 150 swings (movement, pivotable), coupling 150 does not interfere with each other with gear 147.Space 147a is arranged on the central part office of gear 147.Like this, the length of coupling 150 can be shortened.In addition, with regard to the installation method of gear 147, hole 147b (Figure 59 (b)) is rotatably supported by the back shaft (not shown) of development supporting member 11151.In addition, cylindrical shape part 147c is rotatably supported by the inside surface 11157i of supporting member 11157.
Because the joint that coupling is undertaken by the rotation process of rotary body C, driving and disengaging are identical with embodiment 1, therefore omit it and describe.
Either method in aforesaid embodiment 2 to embodiment 5 can be adopted for axis L2 being tilted to before will engaging with driving shaft at coupling the pre-device engaging Angle Position.
As described with reference to present embodiment, not coupling 150 must be arranged at the end coaxial with developer roll 110.More specifically, according to above-mentioned embodiment, coupling 150 is arranged on vertical direction along the axis L1 direction of developer roll 110 away from the position of the axis L1 of developer roll 110.Further, along the direction of rotation L2, revolving force transmits surface (revolving force transmitting portions, Delevoping cartridge sideway swivel power transmitting portions) 150h and is arranged on and revolving force receiving surface (revolving force receiving unit) side that 150e is relative.The revolving force being transmitted surperficial 150h reception by revolving force is delivered to developer roll 110 by passing pin 155 (revolving force receiving unit) and gear 145 and 147 (driving force transmission member).Like this, developer roll 110 is rotated by the revolving force received from equipment master component A by coupling 150.
According to this embodiment, increase the flexible design degree of equipment master component A and Delevoping cartridge B.This is because in Delevoping cartridge B, no matter how, the position of coupling all can suitably be selected in the position of developer roll 110.
In addition, in equipment master component A, under the state that Delevoping cartridge B is installed on rotary body C, no matter how, the position of driving shaft 180 all can suitably be selected in the position of developer roll 110.
This improvement for commercial product is effective.

In this embodiment, coupling 12150 comprises secondary part 12150a, center section 12150c and drive part 12150b.Method of attachment between them describes in drum flange assemble method later.
See Figure 62, the example of the development shaft end component 12151 supporting coupling 12150 will be described.Figure 62 (a) illustrates the view observed from drive shaft side, and Figure 62 (b) is along the cut-open view crossed by the line S22-S22 in Figure 62 (a).
Opening 12151g1 or 12151g2 shown in Figure 62 (a) forms the groove of the rotation direction extension along development shaft end component 12151.When installing coupling 12150, revolving force passing pin (revolving force transmitting portions) 12155 enters in this opening 12151g1 or 12151g2.
Passing pin 12155 is mobile in opening 12151g1 or 12151g2 inside.Like this, be in which kind of rotatable phase regardless of the developer roll 110 in Delevoping cartridge B5, coupling 12150 can move between described three Angle Position.
In addition, in Figure 62 (a), revolving force receiving surface (revolving force receiving unit) 12151h (12151h1 or 12152h2) is arranged on the clockwise upstream end of opening 12151g1 or 12151g2.Surperficial 12151h is transmitted in the sidepiece contact of the passing pin 12155 of coupling 12150.Like this, revolving force is delivered to developer roll 110.Transmit surperficial 12151h1 to 12151h2 and there is the surface intersected with the sense of rotation of end member 12151.Like this, transmit the side that surperficial 12151h is pressed against passing pin 12155, and rotate (Figure 62 b) around axis L1.

Figure 62 (d) is the cut-open view that step coupling 12150 being fixed to end member 12151 is shown.
Coupling 12150 moves along X33 direction, and transmitting portions 12150b inserts in accommodating part 12151j.Retaining member 12156 inserts along arrow X33 direction to be fixed on end member 12151.Retaining member 12156 is fixed in the mode that there is play with align member 12150q.Like this, coupling 12150 can change orientation.In this way, the coupling unit with coupling integrally and end member 12151 is provided.
Retaining part 12156i installs coupling 12150, makes coupling 12150 to transmit Angle Position, pre-joint Angle Position at revolving force and to depart between Angle Position and moves (pivotable).In addition, retaining part 12156i adjusts the amount of movement of coupling 12150 along axis L2 direction.In other words, opening 12156j has the diameter of phi D15 less than the diameter of retaining part 12156i.
With projection 12150d analogously, revolving force transmit surface (revolving force transmitting portions) 12150h1 or 12150h2 be preferably arranged on circumferentially same diametrically.
By said structure, coupling and end member can be treated integratedly.Like this, operation during assembling becomes easy, and can realize improving assembling property.
See Figure 63 and Figure 64, the installation of Delevoping cartridge B will be described.Figure 63 (a) is the stereographic map of major part of the Delevoping cartridge observed from driving side, and Figure 63 (b) is the stereographic map of the major part of the Delevoping cartridge observed from non-drive side.In addition, Figure 64 is along the cut-open view crossed by the line S23-S23 in Figure 63 (a).Developer roll 110 is rotatably arranged on developing device frame 119.
In description above, coupling 12150 and end member 12151 are assembled into coupling unit.This unit U10 is installed on development axle 12153 by the side of developer roll 110 end, makes to expose transmitting portions 12150a.Further, transmitting portions 12150a assembling is through the inner space 12157b of supporting member 12157.Like this, transmitting portions 12150a exposes through Delevoping cartridge.
As shown in Figure 64, supporting member 12157 is provided with the localization part 12157e for developer roll 12110.Like this, just reliably end member 12151 is maintained.
At this, as shown in Figure 66, the axis L2 of coupling 12150 can tilt along any direction relative to axis L1.Figure 66 (a1) to 66 (a5) is the view observed from driving shaft 180 side, and Figure 66 (b1) is its stereographic map to 66 (b5).In Figure 66 (a1) and 66 (b1), axis L2 and axis L1 is coaxial.Figure 66 (a2) and 66 (b2) illustrates from the coupling 12150 the acclivitous state of described state.When coupling is towards the inclined position of opening 12151g, passing pin 12155 moves (Figure 66 (a2), 66 (b2)) along opening 12151g.As a result, coupling 12150 tilts around the axis AX perpendicular to opening 12151g.
In Figure 66 (a3) and 66 (b3), coupling 12150 is tilted to the right.Therefore, when coupling along opening 12151g orthogonal directions tilt time, pin 12155 is at opening 12151g internal rotating.Rotation is the axis AY of passing pin 12155.
The coupling 12150 downward-sloping coupling 12150 being shown respectively in Figure 66 (a4), 66 (b4) and 66 (a5), 66 (b5) and being tilted to the left.Coupling 12150 tilts around rotation AX, AY.
Circumference around axis AX rotates and circumference around AY rotates and can be bonded to each other, to allow the inclination on the direction being different from above-mentioned vergence direction, direction between above-mentioned vergence direction.Such as, the direction being different from above-mentioned vergence direction is the directional combination of the directional combination of Figure 66 (a2) and 66 (a3), 66 (a3) and 66 (a4), the directional combination of 66 (a4) and 66 (a5) and the directional combination of 66 (a5) and 66 (a2).In this way, axis L2 can tilt along any direction relative to axis L1.
But axis L2 need not can be pivoted to predetermined angular along any dimension linear within the scope of 360 degree relative to axis L1.In this case, such as, opening 12151g along the circumferential direction sets slightly wide.By this setting, when axis L2 tilts relative to axis L1, even when it can not tilt to predetermined angular linearly, coupling 12150 also can rotate minute angle around axis L2.Like this, axis L2 can tilt to predetermined angular relative to axis L1.In other words, the play along sense of rotation of opening 12151g suitably can be selected by those skilled in the art.
As previously described (Figure 64), spherical surface 12150i contacts retaining part 12156i.Therefore, the rotation of coupling 12150 passes through the center P2 of spherical surface 12150i.In other words, no matter which kind of phase place end member 12151 is in, and axis L2 all can pivotable.In addition, as hereinafter by description, in order to make coupling 12150 engage with driving shaft 180, axis L2 tilted towards the downstream relative to sense of rotation X4 relative to axis L1 before will engaging.In other words, as seen in figure 67, axis L2 tilts relative to axis L1, makes secondary part 12150a be positioned at downstream relative to sense of rotation X4.
Figure 60 illustrates the state that axis L2 tilts relative to axis L1.In addition, Figure 65 is along the cut-open view crossed by the line S24-S24 in Figure 60.
By previously described structure, the axis L2 under heeling condition shown in Figure 65 also can become almost parallel with axis L1.In addition, determine the maximum possible inclined angle alpha 4 (Figure 65) between axis L1 and axis L2, make it contain the scope of the position of secondary part 12150a and center section 12150c contact end portion component 12151 or supporting member 12157.Further, angle α 4 is set as being installed on equipment master component and from the value needed for the dismounting of equipment master component.
At this, in this case, maximum possible inclined angle alpha 4 is 20 degree to 80 degree.
As above with reference to embodiment 1 describe, just before Delevoping cartridge B (B5) arrives the precalculated position of equipment master component A, or with arrive precalculated position roughly side by side, coupling 12150 and driving shaft 180 are engaged with each other.More specifically, just stop roughly side by side before rotary body C stops or with rotary body C, coupling 12150 and driving shaft 180 are engaged with each other.
See Figure 67, the bonding operation of this coupling 12150 will be described.Figure 67 is the longitudinal sectional view of the equipment master component A from low portion observation.
In the process of Delevoping cartridge B7 by rotary body C and movement, the axis L2 of coupling 12150 to tilt in advance along sense of rotation X4 relative to axis L1 and engages Angle Position in advance (Figure 67 a).Due to this inclination of coupling 12150, on the direction of axis L1, relative to the position of free end position, the downstream 12150A1 of sense of rotation X4 than driving shaft free end 180b3 closer to side, developer roll 12110 direction.In addition, relative to the position of free end position, the upstream 12150A2 of sense of rotation X4 than driving shaft free end 180b3 closer to side, pin 182 direction (Figure 67 (a)).
First, the passing through from driving shaft free end 180b3 side relative to free end position, the downstream 12150A1 of sense of rotation X4 of coupling 12150.Through afterwards, a part (receiving surface 12150f and/or projection 12150d)---i.e. Delevoping cartridge side contacts part---contact master component side engagement part (driving shaft 180 and/or pin 182) for coupling.In response to the rotation of rotary body C, coupling tilts, and makes axis L2 parallel with axis L1 (Figure 67 (c)) gradually.Further, when finally stopping at precalculated position (developing location) in equipment master component A as Delevoping cartridge B7 (rotation of rotary body stops), driving shaft 180 and developer roll 12110 will become roughly coaxial each other.Further, coupling 12150 transmits Angle Position towards the revolving force that axis L2 and axis L1 is roughly coaxial move from the pre-Angle Position that engages.Further, coupling 12150 and driving shaft 180 are engaged with each other (Figure 67 (d)).The recess 12150z of coupling covers free end 180b.
As previously described, coupling 12150 is installed relative to axis L1 inclination movement.More specifically, in response to the rotation of rotary body C, the situation that coupling 12150 is not being interfered with driving shaft 180 has a down dip.Like this, coupling 12150 can engage with driving shaft 180.
Similar to embodiment 1, be in which kind of phase place regardless of driving shaft 180 and coupling 12150, all can implement the bonding operation of above-mentioned coupling 12150.
In this way, in this embodiment, coupling 12150 is installed on Delevoping cartridge B7 in the mode substantially rotated relative to developer roll 110.
See Figure 68, by the revolving force transmission operation described when rotating developer roll 110.Driving shaft 180 rotates along X8 direction together with gear (spiral gear) 181 due to the revolving force received from motor 64 (drive source).Two in four revolving force receiving surface 150e of coupling 12150 are contacted, to rotate coupling 12150 with the passing pin 182 of driving shaft 180 one.In addition, as mentioned before, coupling 12150 and developer roll 110 are coupled to carry out driving and transmit.Therefore, the end member 12151 that is rotated through of coupling 12150 makes developer roll 110 rotate.
In addition, even if axis L3 and axis L1 departs from coaxial relation slightly, because coupling 12150 just tilts slightly, therefore coupling also can rotate and can not execute Increased Load to developer roll and driving shaft.
This is according to one of remarkable result of coupling embodiment of the present invention.
See Figure 69, by the operation of parts such as coupling 12150 grade be described in Delevoping cartridge B (B7) to move to another location during by the rotation of rotary body C.Figure 69 is the longitudinal sectional view of the equipment master component A from low portion observation.First, similar to embodiment 1, when no matter when Delevoping cartridge B is mobile from the position (developing location) relative with photosensitive drums, pin 182 is arranged in any two places (Figure 61) of intake section 12150k1 to 12150k4.
At rotary body C under the state of developing location stall, the axis L2 of coupling 12150 is roughly coaxial relative to axis L1 (revolving force transmission Angle Position).When rotary body C starts further along unidirectional rotation after development terminates, in response to the movement along sense of rotation X4 of Delevoping cartridge B (developer roll 110), (Figure 69 a) for the free end 180b of the upstream receiving surface 12150f relative to sense of rotation X4 of coupling 12150 and/or projection 12150d contact driving shaft 180 and/or pin 182.Further, axis L2 starts (Figure 69 b) towards the upstream oblique relative to sense of rotation X4.Relative to axis L1, this vergence direction is roughly reverse with the vergence direction (engaging Angle Position in advance) of the coupling when Delevoping cartridge B moves to developing location in the direction.By the rotation process of this rotary body C, move relative to the upstream free end 12150A2 of sense of rotation X4, simultaneously its contact driving shaft 180 (free end 180b).The axis L2 of coupling 12150 tilts to the position (disengaging Angle Position) that upstream free end 12150A2 arrives driving shaft free end 180b3 (Figure 69 c).Further, in this state, coupling 12150 passes through (Figure 69 d) from it while maintenance contacts with driving shaft free end 180b3.Thereafter, Delevoping cartridge B is fully withdrawn from developing location by the rotation process of rotary body C.
As previously described, coupling 12150 is to be installed on Delevoping cartridge B relative to the mode of axis L1 inclination movement.Further, in response to the rotation of rotary body C, the situation that coupling 12150 is not being interfered with driving shaft has a down dip.Like this, coupling 12150 can depart from driving shaft 180.
By means of said structure, coupling 12150 can process integratedly with end member (gear etc.).Therefore, assembly operation performance is improved.
For the axis L2 of coupling being tilted to before will engaging with driving shaft at coupling any one that the pre-structure engaging Angle Position can adopt in embodiment 2 to embodiment 5.
[embodiment 11]
See Figure 70, Figure 71 and Figure 72, embodiment 11 will be described.
Present embodiment is in the position (being coupled position) of input queued switches and revolving force is delivered to the configuration aspects of developer roll and developer feeding roller from coupling different from embodiment 10.
Figure 70 is the stereographic map of Delevoping cartridge according to the present embodiment.Figure 71 is the stereographic map of the drive part that Delevoping cartridge is shown.Figure 72 is the stereographic map of the driving input gear from driving side observation.Figure 72 (b) is the stereographic map of the driving input gear from non-drive side observation.
Developing gear 145 and donor rollers gear 146 are separately positioned on the driving side end of developer roll 110 and donor rollers 115 (Fig. 1).Gear 145 and 146 is fixed on axle.The revolving force received from equipment master component A by coupling 13150 is delivered to other rotating member (developer roll 110, developer feeding roller 115, toner stirring apparatus (not shown) etc.) of Delevoping cartridge B (B6) by gear.
To the driving input gear 13147 supporting coupling 13150 be described.
As shown in Figure 71, gear 13147 is rotatably arranged on the position for engaging with developing gear 145 and donor rollers gear 146.Gear 13147 has the coupling accommodating part 13147j (Figure 72 (a)) similar to the end member 12151 described in embodiment 10.Coupling 13150 is pivotally remained on gear 13147 by retaining member 13156.
Further, supporting member 13157 and tilt adjustment mechanism 13157i are installed on (Figure 70) on Delevoping cartridge B.
Supporting member 13157 arranges porose, and the inside surface 13157i of supporting member 13157 engages with gear 13147.Because the joint that coupling is undertaken by the rotation process of rotary body, driving and to depart from embodiment 10 identical, therefore for the sake of brevity omit its description.
In addition, for the axis L2 of coupling being tilted to before will engaging with driving shaft at coupling any one that the pre-structure engaging Angle Position can adopt in embodiment 2 to embodiment 5.
As mentioned before, not coupling must be arranged on the end coaxial with developer roll.According to this embodiment, the flexibility ratio of the design aspect of imaging device and Delevoping cartridge can be increased.The effect similar to embodiment 9 is embodiment there is provided according to this.
[embodiment 12]
With reference to Figure 73 and Figure 74, embodiment 12 is described.
In the foregoing embodiment, the example using rotation selection mechanism (rotary body) as the mobile member of developing apparatus (Delevoping cartridge B) is described.In this embodiment, another mobile member will be described.
Figure 73 (a) and 73 (b) are the cut-open views of the Delevoping cartridge supporting member illustrated for supporting four Delevoping cartridge B (14B1 to 14B4).Figure 74 (a) is illustrate for coupling and driving shaft being engaged and the stereographic map of the process be separated and side view to 74 (e).
See Figure 73 (a) and 73 (b), with regard to xsect, each Delevoping cartridge B (14B1 to 14B4) is horizontally installed in Delevoping cartridge supporting member 14190, and is removably installed on Delevoping cartridge supporting member 14190.The schematic diagram of Figure 73 (a) shows the first color development box 14B1 and is positioned at the part place relative with photosensitive drums 107 and can performs the state of development relative to photosensitive drums 107.When Delevoping cartridge 14B1 completes development, supporting member 14190 moves along X20 direction, makes adjacent (second) color development box 14B2 be positioned at the part place (developing location) relative with photosensitive drums 107.Say one along band, be formed in developer image in photosensitive drums 107 on transfer belt 104a.These operations are all repeated to often kind of color.Finally, as shown in Figure 73 (b), the 4th color development box 14B4 moves to the part relative with photosensitive drums 107, and four kinds of color developers images are transferred in transfer belt.Then, developer image is transferred to recording materials S from transfer belt, and fixing on recording materials S.
Say one along band, by supporting member 14190 along unidirectional movement, each Delevoping cartridge 14B moves along roughly vertical with the axis L3 direction of driving shaft 180 direction.
As a result, recording materials S forms coloured image.
When completing a series of colour imaging, supporting member 14190 moves along X21 direction to get back to initial position (state of Figure 73 (a)).
Next, see Figure 74 (a) to 74 (e), the movement being described through supporting member is connected and the step be separated to make coupling with driving shaft.
Typically, by the connection describing Delevoping cartridge 14B3 and coupling 14150C be separated.Figure 74 (a) be illustrate coupling 14150C will be connected with driving shaft 180 before the stereographic map of state, and Figure 74 (b) is its side view.Figure 74 (c) be illustrate that coupling is connected to driving shaft and is placed in can the stereographic map of state in transmission of drive force situation.Figure 74 (d) is the stereographic map that coupling and driving shaft released state are shown, Figure 74 (e) is its side view.
In this embodiment, the structure described in embodiment 5 is used to be used as the device of tilt axis L2.That is, be arranged at the adjustment rib 14191 on equipment master component and arrange along the downside of the circuit L20 of coupling 14150C process, and be arranged on the upstream of driving shaft 180 relative to moving direction X20.Further, with embodiment 6 similarly, the distance between the adjustment top surface 14191a of rib and coupling 14150C is set as when coupling 14150C diminishes close to during driving shaft 180.Further, as shown in Figure 74 (b), the vergence direction of adjustment axis L, makes secondary part (part to be driven) 14150Ca be upwardly directed (vergence direction is indicated by line L30) relative to circuit L20.
At this, when completing the development of Delevoping cartridge 14B2, supporting member is along one direction translation.By this translation, Delevoping cartridge 14B3 moves towards precalculated position.In this process, center section 14150Cc contacts top surface 14191a.Now, as described in embodiment 6, secondary part 14150Ca is guided towards driving shaft 180 (engaging Angle Position in advance) (state of Figure 74 (a)).Thereafter, with description above similarly, coupling 14150C engages with driving shaft 180 (revolving force transmission Angle Position) (state of Figure 74 (c)).Then, when completing the imaging of Delevoping cartridge 14B3, Delevoping cartridge 14B3 moves along X20 direction.Coupling 14150C and driving shaft 180 depart from (disengaging Angle Position) (state of Figure 74 (d)).Its details is identical with above-mentioned those, therefore omits.
As mentioned above, when completing development by all couplings, supporting member 14190 gets back to initial position (state of Figure 74 (b)).Be described to the operation in this process.Require that the coupling of each Delevoping cartridge is all by driving shaft 180.Therefore, with in developing process similarly, coupling transmits Angle Position through revolving force move to disengaging Angle Position from the pre-Angle Position that engages.For this purpose, the structure for tilt axis L2 must be adopted.As shown in Figure 74 (d), the upside of the circuit L20 passed through along coupling 14150C to the similar adjustment rib 14192 described in embodiment 6 is arranged.Adjustment rib 14192 is arranged at the upstream of driving shaft 180 relative to moving direction X21.Further, the distance adjusted between rib 14192 and circuit L20 similarly sets with the situation of adjustment rib 14191.That is, adjust rib 14191 to be set as becoming point symmetry relation relative to the center of driving shaft 180 with adjustment rib 14192.Say one along band, as shown in Figure 74 (e), the adjustment direction of coupling 14150C does not change.Therefore, by the identical operation with (along in the moving process in X20 direction) in imaging (development) process, in starting stage (X21 direction), coupling 14150C also moves to disengaging Angle Position from the pre-Angle Position that engages through revolving force transmission Angle Position.In this operating process, coupling 14150C, by driving shaft 180, then gets back to initial position.
In this embodiment, Delevoping cartridge removably supports relative to imaging device.In the replacement process of Delevoping cartridge, as shown in Figure 74 (a), supporting member 14190 rotatably moves along X30 direction.By this rotary motion, each in Delevoping cartridge 14B1 to 14B4 is moved to the position that can replace by user.
Say one along band, in this embodiment, the moving direction of Delevoping cartridge is obliquely, but also can be contrary direction, and Delevoping cartridge can be set to can move along other direction.
In description above, be embodied as picture (development) when Delevoping cartridge moves along one direction, and picture (development) can not be embodied as when Delevoping cartridge moves along other direction.But the present invention is not limited thereto.Such as, when Delevoping cartridge moves along other direction, picture can be embodied as.
[embodiment 13]
With reference to Figure 75, embodiment 13 is described.
In description above, describe the Delevoping cartridge being removably installed on equipment master component.In this embodiment, provide such imaging device: the developing apparatus as developing apparatus is fixed to equipment master component, and be embodied as picture by real-time supply developer.That is, the developing apparatus in this embodiment is installed on equipment master component A by user, but does not dismantle.Developing apparatus in this embodiment is fixed, and wherein developing apparatus is fixed to equipment master component A and uses in the stationary state.Safeguard and performed by attendant.
Figure 75 is the cut-open view of equipment master component.
As shown in Figure 75, rotary body C2 comprises developing apparatus 15A, 15B, 15C and 15D of installation four kinds of colors in the inner.Rotary body C2 comprises further and being respectively used to developer feeding developer reservoir 16A, 16B, 16C and 16D to relevant developing apparatus.These containers 16A, 16B, 16C and 16D are installed on equipment master component A in the mode can dismantled along the direction perpendicular to the accompanying drawing page.When developer in container is empty time, change container by user.
By the rotation of rotary body C2, each developing apparatus 15A, 15B, 15C and 15D move to the part (developing location) relative with photosensitive drums 107 in succession, and in this counterpart office, make to be formed in the image development in photosensitive drums 107.According to the movement of each developing apparatus to described opposite segments, the coupling member (not shown) be arranged on developing apparatus engages with the driving shaft (not shown) being arranged at equipment master component.Thereafter, when completing imaging, Delevoping cartridge (not shown) and driving shaft depart from.This operation and embodiment 1 etc. are similar, therefore omit it and describe.
As mentioned above, even when the driving being fixed to the developing apparatus on equipment master component switches, this operation still similarly can be carried out with aforementioned embodiments.
[embodiment 14]
With reference to Figure 76, Figure 77 and Figure 78, embodiment 14 is described.
These embodiments coupling structure and for coupling is maintained pre-engage in the arranging of the resilient material of Angle Position different from embodiment 11.
Figure 76 (a) is the stereographic map of the part that Delevoping cartridge B is shown.Figure 76 (b) is the line that extends along the vergence direction of the axis along coupling and through the cut-open view (install and drive the component of input gear to be also illustrated) crossed by the center of input gear of overdriving.Figure 77 (a) is coupling side view alone.Figure 77 (b) is coupling stereographic map alone.Figure 78 (a) illustrates that coupling (Delevoping cartridge) is positioned at the pre-cut-open view engaging the state of Angle Position.Figure 78 (b) illustrates that coupling (Delevoping cartridge) is positioned at the cut-open view that revolving force transmits the state of Angle Position.Figure 78 (c) illustrates that coupling (Delevoping cartridge) is positioned at the cut-open view of the state departing from Angle Position.Figure 78 (a), (b) and (c) illustrate the position relationship between coupling 15150 and driving shaft 180.
As shown in Figure 76, developing gear 145 is arranged at the end of developer roll 110.Further, developing gear 145 is fixed on the axle 155 of developer roll 110.
To the driving input gear 15147 installing coupling 15150 be described below.
As shown in Figure 76, gear 15147 have for developing gear 145 meshed gears part 15147a and for donor rollers gear 146 (Figure 58) meshed gears part 15147b.Further, gear 15147 is rotatably installed on Delevoping cartridge B by supporting member 15170 and supporting member 15157.Supporting member 15170 is also as the supporting member of developer roll 110.
Like this, transmit surperficial 12151h (Figure 62 (a), (b), revolving force receiving unit), gear 147 and gear 145 from the revolving force that equipment master component A receives by pin 15155 (revolving force transmitting portions), revolving force by coupling 15150 and be delivered to developer roll 110.
Coupling 15150 is pivotally installed on gear 15147 (can move between described three Angle Position) by retaining part 15147m.In addition, coupling 15150 is loaded by loading spring (resilient material) 15159, engages Angle Position in advance to maintain.In this embodiment, spring 15159 is helical torsion springs.The support section 15159a of spring 15159 is locked by the mounting portion (not shown) be arranged on Delevoping cartridge B.Further, the center section 15150c of arm section 15159b to coupling of spring 15159 flexibly loads.Like this, the axis L2 of coupling 15150 maintains and engages Angle Position (Figure 78 (a)) in advance.In the present embodiment, the spring force (elastic force) of spring 15159 is 5g to 100g.If spring force is lower than 5g, then due to factors such as friction force, coupling may not correctly tilt.If spring force is higher than 100g, then, when coupling rotates, the contact portion of spring may be scraped.But, according to the condition such as structure and material of such as wire diameter and spring material, coupling, this extraneous spring force can be adopted.In addition, also helical torsion spring is not limited to.
More specifically, spring 15159 (resilient material) flexibly loads coupling 15150.The elastic force of spring 15159 makes it coupling 15150 can be maintained and engages Angle Position in advance, simultaneously spring 15159 is allowed coupling is moved to revolving force transmit Angle Position (Figure 78 (b)) from the pre-Angle Position that engages, and allows that coupling 15150 is transmitted Angle Position from revolving force to be moved to and depart from Angle Position (Figure 78 (c)).
This is also applicable to the spring (resilient material) 4159 described by embodiment 3 grade.
Further, Delevoping cartridge B has the tilt adjustments part of the vergence direction for adjusting coupling.Because this structure is identical with embodiment 11, therefore for the sake of brevity omits it and describe.
As shown in Figure 77, coupling 15150 is different in the structure of secondary part 15150a from the coupling 12150 described in embodiment 11.
More specifically, the opening 15150m of secondary part 15150a is provided with recess 15150z and flat 15150y.Recess 15150z contacts the free end 180b (Figure 78 (b)) of driving shaft 180.As shown in Figure 78, when coupling 15150 is in time engaging Angle Position (Figure 78 (a)) in advance and arrive revolving force transmission Angle Position (Figure 78 (b)), the revolving force of driving shaft 180 will be delivered to coupling 15150 by pin 182.In this embodiment, driving shaft 180 side is flat 15150y instead of recess 15150z.Like this, the flat 15150y of the peripheral part 182d (Figure 78 (a), (b), (c)) of pin 182 and coupling can (Figure 78 (b)) closer to each other.
Like this, Delevoping cartridge B and equipment master component can shorten along the length of axis L1, L3.Therefore, Delevoping cartridge B and equipment master component can reduce size.
At this, the internal diameter Z1=of the flat 15150y of coupling used in this embodiment is about Φ 5mm.In addition, its external diameter Z2=is about Φ 11mm.In addition, the degree of depth Z3=of flat is about 0.6mm.In addition, the degree of depth of the recess 15150z of cone shape is about 1.5mm at the top section of conical by its shape, and its diameter is about 5mm.In addition, the weight of coupling 15150 is about 1.5g.In this embodiment, the material of coupling is polyacetal resin.But the value of these sizes and weight is not required, and those skilled in the art suitably can select them.
In addition, in the present embodiment, the projection 15150d (15150d1,15150d2) of coupling is separately positioned on two positions.Like this, along intake section 150k (150k1,150k2) circumference measured by width can increase.Therefore, pin 182 can enter intake section 150k reposefully.Although the quantity of projection can suitably be selected, preferably there is multiple projection.This is because revolving force can transmit accurately.
Because coupling structure in addition and its operation being engaged by the rotation process of rotary body, drive and depart from are identical with embodiment 10, therefore omit description for the sake of brevity.
In addition, the structure for the axis of coupling being tilted to pre-joint Angle Position can adopt any one in embodiment 2 to embodiment 5.
In addition, in this embodiment, coupling 15150 is arranged on vertical direction along axis L1 away from the position (Figure 76 (b)) of axis L1.
